GSI Technology, Inc.

We develop and market "Very Fast" static random access memory, or SRAM, products that are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, we serve the ongoing needs of the military, industrial, test equipment and medical markets for high-performance SRAMs. Gartner Dataquest divides the SRAM market into segments based on speed. The highest performance segment is comprised of SRAMs that operate at speeds of less than 10 nanoseconds, which we refer to as "Very Fast SRAMs." Gartner Dataquest estimates that this segment of the SRAM market will be greater than $1 billion in 2007. Based on the performance characteristics of our products and the breadth of our product portfolio, we consider ourselves to be a leading provider of Very Fast SRAMs.

We believe the key success factors for a Very Fast SRAM vendor are the ability to offer a broad catalog of high-performance, high-quality and high-reliability Very Fast SRAM products, to continuously introduce new products with higher speeds, lower power consumption and greater memory capacity, or density, to maintain timely availability of prior generations of products for several years after their introductions, and to provide effective logistic and technical support throughout our customers' product development and manufacturing life cycles. Accordingly, the key elements of our solution include:

•: Innovative Product Performance Leadership. We believe that through the use of advanced architectures, design methodologies and silicon process technologies, we have established a position as a technology leader in the design and development of Very Fast SRAMs. The vast majority of our products have random access times of 9 nanoseconds or less, while our newest products have random access times of less than 5 nanoseconds and clock access times as fast as 0.45 nanoseconds. Many of our Very Fast SRAMs require significantly less power than comparable products offered by our principal competitors.
•: Broad and Readily Available Product Portfolio. To meet our customers' diverse needs, we have what we believe is the broadest catalog of Very Fast SRAM products currently available, with features that address a wide range of our networking and telecommunications customers' system requirements. Additionally, we commit to manufacture our products for seven years or more following their initial introduction, which is generally longer than our competitors.
•: Master Die Methodology. Our use of master die designs enables multiple product families to be manufactured from a single mask set. This allows us to respond to unforecasted customer orders more quickly than our competitors and reduce our costs through the purchase of fewer mask sets by enabling more cost-efficient use of engineering resources and by reducing the incidence of obsolete inventory.

•: Customer Responsiveness. We work closely with leading networking and telecommunications original equipment manufacturers, or OEMs, as well as their chip-set suppliers, to better anticipate their requirements and to rapidly develop and implement solutions that allow them to meet their specific product performance objectives. Our customer driven approach provides our OEM customers with high-quality and high-reliability products and helps them accelerate their time-to-market.

Our objective is to profitably increase our market share in the Very Fast SRAM market by:

•: continuing to focus on the networking and telecommunications markets;
•: strengthening and expanding our customer relationships;
•: continuing to invest in research and development to extend our technology leadership; and
•: collaborating with wafer foundries to leverage leading-edge process technologies.

We sell our products to leading networking and telecommunications OEMs, including Alcatel-Lucent, Cisco Systems, Huawei Technologies and Nortel Networks. We utilize a fabless business model, which allows us both to focus our resources on research and development, product design and marketing, and to gain access to advanced process technologies with only modest capital investment and fixed costs.

Cisco Systems is our largest OEM customer and accounted for between 28% and 34% of our net revenues in each of our last three fiscal years and the nine months ended December 31, 2006. We expect Cisco Systems to account for a lesser percentage of our net revenues for the quarter ending March 31, 2007. Cisco Systems has announced the implementation of a "lean manufacturing" program under which it plans to reduce the levels of inventory carried by it and by its contract manufacturers. We believe that the transition to this new program will result in reductions in purchases of our products by Cisco Systems' contract manufacturers during the quarter ending March 31, 2007, as they draw down their existing inventories, and that such reductions will likely result in our net revenues for the quarter being less than in the previous quarter. This transition could also impact our revenues in the quarter ending June 30, 2007.

We were incorporated in California in 1995 under the name Giga Semiconductor, Inc. We changed our name to GSI Technology in December 2003 and reincorporated in Delaware in June 2004 under the name GSI Technology, Inc.

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and all of the other information contained in this prospectus before deciding whether to purchase our common stock. If any of the following risks actually occur, our business, financial condition and results of operations would suffer. In such case, the trading price of our common stock could decline, and you may lose all or part of your investment in our common stock. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.

Risks Related to Our Business and Our Industry

Unpredictable fluctuations in our operating results could cause our stock price to decline.

Our quarterly revenues, expenses and operating results have varied significantly from quarter to quarter and are likely to vary in the future. For example, in the seven most recent fiscal quarters ended December 31, 2006, we have recorded net revenues of as much as $15.3 million and as little as $10.4 million and quarterly operating income of as much as $3.4 million and as little as $508,000. We therefore believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance, and you should not rely on them to predict our future performance or the future performance of our stock price. You should not consider recent quarterly revenue growth as an indication of our future performance. In fact, as described below, we expect our net revenues for the quarter ending March 31, 2007 to be less than for the previous quarter due to the implementation of a new inventory system by Cisco Systems, our largest OEM customer. In other future quarters, we may not have any revenue growth, or our revenues could decline. Furthermore, if our operating expenses exceed our expectations, our financial performance will be adversely affected. Factors that may affect quarterly operating results in the future include:

•: our ability to attract new customers, retain existing customers and increase sales to such customers;
•: unpredictability of the timing and size of customer orders, since most of our customers purchase our products on a purchase order basis rather than pursuant to a long term contract;
•: changes in our customers' inventory management practices;
•: fluctuations in availability and costs associated with materials needed to satisfy customer requirements;
•: manufacturing defects, which could cause us to incur significant warranty, support and repair costs, lose potential sales, harm our relationships with customers and result in write-downs;
•: changes in our product pricing policies, including those made in response to new product announcements and pricing changes of our competitors; and
•: our ability to address technology issues as they arise, improve our products' functionality and expand our product offerings.

Our expenses are, to a large extent, fixed, and we expect that these expenses will increase in the future. We will not be able to adjust our spending quickly if our revenues fall short of our expectations. If this were to occur, our operating results would be harmed. If our operating results in future quarters fall below the expectations of market analysts and investors, the price of our common stock could fall.

Cisco Systems, our largest OEM customer, accounts for a significant percentage of our net revenues. If Cisco Systems, or any of our other major customers reduce the amount they purchase or stop purchasing our products, our operating results will suffer.

Cisco Systems, our largest OEM customer, purchases our products through SMART Modular Technologies, its consignment warehouse, through its contract manufacturers and directly from us. Based on information provided to us by consignment warehouses and contract manufacturers, purchases by Cisco Systems represented approximately 31%, 34%, 28% and 32% of our net revenues in fiscal 2004, 2005 and 2006 and the nine months ended December 31, 2006, respectively. We expect Cisco Systems to account for a lesser percentage of our net revenues for the quarter ending March 31, 2007. Cisco Systems has announced the implementation of a "lean manufacturing" program under which it plans to reduce the levels of inventory carried by it and by its contract manufacturers. We believe that the transition to this new program will result in reductions in purchases of our products by Cisco Systems' contract manufacturers during the quarter ending March 31, 2007, as they draw down their existing inventories, and that such reductions will likely result in our net revenues for the quarter being less than in the previous quarter. This transition could also impact our revenues in the quarter ending June 30, 2007.

We expect that our operating results in any given period will continue to depend significantly on orders from our key OEM customers, particularly Cisco Systems, and our future success is dependent to a large degree on the business success of these OEMs over which we have no control. We do not have long-term contracts with Cisco Systems or any of our other major OEM customers, distributors or contract manufacturers that obligate them to purchase our products. If we fail to continue to sell to our key OEM customers, distributors or contract manufacturers in sufficient quantities, the growth of our business could be harmed.

We have incurred significant losses in prior periods and may incur losses in the future.

We have incurred significant losses in prior periods. For example, in fiscal 2003 and 2004, we incurred losses of $7.4 million and $670,000, respectively. Although we have operated profitably during the last two fiscal years, there can be no assurance that our Very Fast SRAMs will continue to receive broad market acceptance or that we will be able to sustain revenue growth or profitability. Our failure to do so may result in additional losses in the future. In addition, we expect our operating expenses to increase as we expand our business. If our revenues do not grow to offset these expected increased expenses, our business will suffer.

We depend upon the sale of our Very Fast SRAMs for most of our revenues, and a downturn in demand for these products could significantly reduce our revenues and harm our business.

We derive most of our revenues from the sale of Very Fast SRAMs, and we expect that sales of these products will represent the substantial majority of our revenues for the foreseeable future. Our business depends in large part upon continued demand for our products in the markets we currently serve, and adoption of our products in new markets. Market adoption will be dependent upon our ability to increase customer awareness of the benefits of our products and to prove their high-performance and cost-effectiveness. We may not be able to sustain or increase our revenues from sales of our products, particularly if the networking and telecommunications markets were to experience another significant downturn in the future. Any decrease in revenues from sales of our products could harm our business more than it would if we offered a more diversified line of products.

We are subject to the highly cyclical nature of the networking and telecommunications markets.

Our products are incorporated into routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment used in the highly cyclical networking

and telecommunications markets. Our operating results declined sharply in fiscal 2002 and 2003 as a result of the severe contraction in demand for networking and telecommunications equipment in which our products are incorporated. Prior to this period of contraction, the networking and telecommunications markets experienced a period of rapid growth, which resulted in a significant increase in demand for our products. We expect that the networking and telecommunications markets will continue to be highly cyclical, characterized by periods of rapid growth and contraction. Our business and our operating results are likely to fluctuate, perhaps quite severely, as a result of this cyclicality.

The average selling prices of our products are expected to decline, and if we are unable to offset these declines, our operating results will suffer.

Historically, the average unit selling prices of our products have declined substantially over the lives of the products, and we expect this trend to continue. A reduction in overall average selling prices of our products could result in reduced revenues and lower gross margins. Our ability to increase our net revenues and maintain our gross margins despite a decline in the average selling prices of our products will depend on a variety of factors, including our ability to introduce lower cost versions of our existing products, increase unit sales volumes of these products, and introduce new products with higher prices and greater margins. If we fail to accomplish any of these objectives, our business will suffer. To reduce our costs, we may be required to implement design changes that lower our manufacturing costs, negotiate reduced purchase prices from our independent foundry, Taiwan Semiconductor Manufacturing Company Limited, or TSMC, and our independent assembly and test vendors, and successfully manage our manufacturing and subcontractor relationships. Because we do not operate our own wafer foundry or assembly facilities, we may not be able to reduce our costs as rapidly as companies that operate their own foundries or facilities.

We rely heavily on distributors and our success depends on our ability to develop and manage our indirect distribution channels.

A significant percentage of our sales are made to distributors and to contract manufacturers who incorporate our products into end products for OEMs. For example, in fiscal 2004, 2005 and 2006, and in the nine months ended December 31, 2006, our distributor Avnet Logistics accounted for 32.0%, 32.5%, 30.4% and 24.2%, respectively, of our net revenues and our distributor Nu Horizons accounted for 3.0%, 6.1%, 10.3% and 8.4%, respectively, of our net revenues. Avnet Logistics, Nu Horizons and our other existing distributors may choose to devote greater resources to marketing and supporting the products of other companies. Since we sell through multiple channels and distribution networks, we may have to resolve potential conflicts between these channels. For example, these conflicts may result from the different discount levels offered by multiple channel distributors to their customers or, potentially, from our direct sales force targeting the same equipment manufacturer accounts as our indirect channel distributors. These conflicts may harm our business or reputation.

We may be unable to accurately predict future sales through our distributors, which could harm our ability to efficiently manage our resources to match market demand.

Our financial results, quarterly product sales, trends and comparisons are affected by fluctuations in the buying patterns of the OEMs that purchase our products from our distributors. While we attempt to assist our distributors in maintaining targeted stocking levels of our products, we may not consistently be accurate or successful. This process involves the exercise of judgment and use of assumptions as to future uncertainties, including end user demand. Inventory levels of our products held by our distributors may exceed or fall below the levels we consider desirable on a going-forward basis. This could result in distributors returning unsold inventory to us, or in us not having sufficient inventory to meet the demand for our products. If we are not able to accurately predict sales through

our distributors or effectively manage our relationships with our distributors, our business and financial results will suffer.

A small number of customers generally account for a significant portion of our accounts receivable in any period, and if any one of them fails to pay us, our operating results will suffer.

At December 31, 2006, SMART Modular Technologies, Avnet Logistics and Nu Horizons accounted for 39.2%, 18.2% and 5.5%, respectively, of our accounts receivable. If any of these customers do not pay us, our operating results will be harmed. Generally, we do not require collateral from our customers.

We could become subject to claims and litigation regarding intellectual property rights, which could seriously harm our business and require us to incur significant costs.

In recent years, there has been significant litigation in the semiconductor industry involving patents and other intellectual property rights. In the past, we have been subject to claims and litigation regarding alleged infringement of other parties' intellectual property rights. In 2002, we settled patent litigation filed against us by one of our competitors. In connection with the settlement, we obtained a license from that competitor and agreed to pay a license fee and ongoing royalties. We could become subject to additional litigation in the future as a result of allegations that we infringe others' intellectual property rights or that our use of intellectual property otherwise violates the law. Claims that our products infringe the proprietary rights of others would force us to defend ourselves and possibly our customers or manufacturers against the alleged infringement. Any such litigation regarding intellectual property could result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations. Similarly, changing our products or processes to avoid infringing the rights of others may be costly or impractical. If any claims received in the future were to be upheld, the consequences to us would be severe and could require us to:

•: stop selling our products that incorporate the challenged intellectual property;
•: obtain a license to sell or use the relevant technology, which license may not be available on reasonable terms or at all;
•: pay damages; or
•: redesign those products that use the disputed technology.

Although patent disputes in the semiconductor industry have often been settled through cross-licensing arrangements, we may not be able in any or every instance to settle an alleged patent infringement claim through a cross-licensing arrangement. We have a more limited patent portfolio than many of our competitors. If a successful claim is made against us or any of our customers and a license is not made available to us on commercially reasonable terms or we are required to pay substantial damages or awards, our business, financial condition and results of operations would be materially adversely affected.

Our business will suffer if we are unable to protect our intellectual property.

Our success and ability to compete depends in large part upon protecting our proprietary technology. We rely on a combination of patent, trade secret, copyright and trademark laws and non-disclosure and other contractual agreements to protect our proprietary rights. These agreements and measures may not be sufficient to protect our technology from third-party infringement, or to protect us from the claims of others. Monitoring unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. Our attempts to enforce our intellectual property rights could be time consuming and

costly. Litigation may be necessary in order to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement. If competitors are able to use our technology without our approval or compensation, our ability to compete effectively could be harmed.

The market for Very Fast SRAMs is highly competitive.

The market for Very Fast SRAMs, which are used primarily in networking and telecommunications equipment, is characterized by price erosion, rapid technological change, cyclical market patterns and heightened foreign and domestic competition. Several of our competitors offer a broad array of memory products and have greater financial, technical, marketing, distribution and other resources than we have. Some of our competitors maintain their own semiconductor fabrication facilities, which may provide them with capacity, cost and technical advantages over us. We cannot assure you that we will be able to compete successfully against any of these competitors. Our ability to compete successfully in this market depends on factors both within and outside of our control, including:

•: real or perceived imbalances in supply and demand of Very Fast SRAMs;
•: the rate at which OEMs incorporate our products into their systems;
•: the success of our customers' products;
•: our ability to develop and market new products;
•: access to advanced process technologies at competitive prices; and
•: the supply and cost of wafers.

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures and new forms of dynamic random access memory, or DRAM, or the emergence of new memory technologies that could enable the development of products that feature higher performance, lower cost or lower power capabilities. Additionally, the trend toward incorporating SRAM into other chips in the networking and telecommunications markets has the potential to reduce future demand for Very Fast SRAM products. There can be no assurance that we will be able to compete successfully in the future. Our failure to compete successfully in these or other areas could harm our business.

We may experience difficulties in transitioning to smaller geometry process technologies and other more advanced manufacturing process technologies, which may result in reduced manufacturing yields, delays in product deliveries and increased expenses.

In order to remain competitive, we expect to continue to transition the manufacture of our products to smaller geometry process technologies. This transition will require us to migrate to new manufacturing processes for our products and redesign certain products. The manufacture and design of our products is complex, and we may experience difficulty in transitioning to smaller geometry process technologies or new manufacturing processes. These difficulties could result in reduced manufacturing yields, delays in product deliveries and increased expenses. We are dependent on our relationships with TSMC to transition successfully to smaller geometry process technologies and to more advanced manufacturing processes. We cannot assure you that TSMC will be able to effectively manage the transition or that we will be able to maintain our relationship with TSMC. If we or TSMC experience significant delays in this transition or fail to implement these transitions, our business, financial condition and results of operations could be materially and adversely affected.

Manufacturing process technologies are subject to rapid change and require significant expenditures for research and development.

We continuously evaluate the benefits of migrating to smaller geometry process technologies in order to improve performance and reduce costs. Historically, these migrations to new manufacturing processes have resulted in significant initial design and development costs associated with pre-production mask sets for the manufacture of new products with smaller geometry process technologies. For example, in the nine months ended December 31, 2005, we incurred $678,000 in research and development associated with pre-production mask sets, which were not later used in production as part of the transition to our new 90 nanometer process technology. We will incur similar expenses in the future as we continue to transition our products to smaller geometry processes. The transition costs inherent in the transition to new manufacturing process technologies will adversely affect our operating results and our gross margin.

Our products are complex to design and manufacture and could contain defects, which could reduce revenues or result in claims against us.

We develop complex products. Despite testing by us and our OEM customers, design or manufacturing errors may be found in existing or new products. These defects could result in a delay in recognition or loss of revenues, loss of market share or failure to achieve market acceptance. These defects may also cause us to incur significant warranty, support and repair costs, divert the attention of our engineering personnel from our product development efforts, result in a loss of market acceptance of our products and harm our relationships with our OEM customers. Our OEM customers could also seek and obtain damages from us for their losses. A product liability claim brought against us, even if unsuccessful, would likely be time consuming and costly to defend.

Defects in wafers and other components used in our products and arising from the manufacturing of these products may not be fully recoverable from TSMC or other suppliers. For example, in the quarter ended December 31, 2005, we incurred a charge of approximately $900,000 related to the write-off of inventory resulting from an error in the assembly process at one of our suppliers. This write-off adversely affected our operating results for fiscal 2006.

We are dependent on a number of single source suppliers, and if we fail to obtain adequate supplies, our business will be harmed and our prospects for growth will be curtailed.

We currently purchase several key components used in the manufacture of our products from single sources and are dependent upon supply from these sources to meet our needs. If any of these suppliers cannot provide components on a timely basis, at the same price or at all, our ability to manufacture our products will be constrained and our business will suffer. For example, we obtain wafers from a single foundry, TSMC. If we are unable to obtain an adequate supply of wafers from TSMC or find alternative sources in a timely manner, we will be unable to fulfill our customer orders and our operating results will be harmed. We do not have supply agreements with TSMC or any of our independent assembly and test suppliers, and instead obtain manufacturing services and products on a purchase-order basis. Our suppliers, including TSMC, have no obligation to supply products or services to us for any specific product, in any specific quantity, at any specific price or for any specific time period. As a result, the loss or failure to perform by any of these suppliers could adversely affect our business and operating results.

Should any of our single source suppliers experience manufacturing failures or yield shortfalls, be disrupted by natural disaster or political instability, choose to prioritize capacity or inventory for other uses or reduce or eliminate deliveries to us, we likely will not be able to enforce fulfillment of any delivery commitments and we would have to identify and qualify acceptable replacements from alternative sources of supply. In particular, if TSMC is unable to supply us with sufficient quantities of

wafers to meet all of our requirements, we would have to allocate our products among our customers, which would constrain our growth and might cause some of them to seek alternative sources of supply. Since the manufacturing of wafers and other components is extremely complex, the process of qualifying new foundries and suppliers is a lengthy process and there is no assurance that we will be able to find and qualify another supplier without materially adversely affecting our business, financial condition and results of operations.

Because we outsource our wafer manufacturing and independent wafer foundry capacity is limited, we may be required to enter into costly long-term supply arrangements to secure foundry capacity.

We do not have long-term supply agreements with TSMC, but instead obtain our wafers on a purchase order basis. In order to secure future wafer supply from TSMC or from other independent foundries, we may be required to enter into various arrangements with them, which could include:

•: contracts that commit us to purchase specified quantities of wafers over extended periods;
•: investments in and joint ventures with the foundries; or
•: non-refundable deposits with or prepayments or loans to foundries in exchange for capacity commitments.

We may not be able to make any of these arrangements in a timely fashion or at all, and these arrangements, if any, may not be on terms favorable to us. Moreover, even if we are able to secure independent foundry capacity, we may be obligated to use all of that capacity or incur penalties. These penalties may be expensive and could harm our financial results.

If we are unable to offset increased wafer fabrication costs by increasing the average selling prices of our products, our gross margins will suffer.

If there is a significant upturn in the networking and telecommunications markets that results in increased demand for our products and competing products, the available supply of wafers may be limited. As a result, we could be required to obtain additional manufacturing capacity in order to meet increased demand. Securing additional manufacturing capacity may cause our wafer fabrication costs to increase. If we are unable to offset these increased costs by increasing the average selling prices of our products, our gross margins will decline.

Demand for our products may decrease if our OEM customers experience difficulty manufacturing, marketing or selling their products.

Our products are used as components in our OEM customers' products. For example, Cisco Systems, our largest OEM customer, incorporates our products in a number of its networking routers and switches. Accordingly, demand for our products is subject to factors affecting the ability of our OEM customers to successfully introduce and market their products, including:

•: capital spending by telecommunication and network service providers and other end users who purchase our OEM customers' products;
•: the competition our OEM customers face, particularly in the networking and telecommunications industries;
•: the technical, manufacturing, sales and marketing and management capabilities of our OEM customers;
•: the financial and other resources of our OEM customers; and
•: the inability of our OEM customers to sell their products if they infringe third-party intellectual property rights.

As a result, if OEM customers reduce their purchases of our products, our business will suffer.

Downturns in the semiconductor industry may harm our revenues and margins.

The semiconductor industry is highly cyclical. The industry has experienced significant downturns, often in connection with, or in anticipation of, maturing product cycles of both semiconductor companies' and their customers' products and declines in general economic conditions. These downturns have been characterized by production overcapacity, high inventory levels and accelerated erosion of average selling prices. From time to time, the semiconductor industry also has experienced periods of increased demand and production capacity constraints.

Our operating results may suffer during the down portion of these cycles. For example, the SRAM industry experienced significant declines in the average selling prices of SRAM products during the recent downturn in the semiconductor industry. We expect similar declines to occur in the future. Downturns in the semiconductor industry could cause our stock price to be volatile, and a prolonged decline in the industry could adversely affect our revenues. If we are unable to control our expenses adequately in response to reduced net sales, our results of operations would be negatively impacted. For example, the industry downturn in 2001 resulted in a $3.9 million inventory write-off in fiscal 2002.

If we do not successfully develop new products to respond to rapid market changes due to changing technology and evolving industry standards, particularly in the networking and telecommunications markets, our business will be harmed.

If we fail to offer technologically advanced products and respond to technological advances and emerging standards, we may not generate sufficient revenues to offset our development costs and other expenses, which will hurt our business. The development of new or enhanced products is a complex and uncertain process that requires the accurate anticipation of technological and market trends. In particular, the networking and telecommunications markets are rapidly evolving and new standards are emerging. We are vulnerable to advances in technology by competitors, including new SRAM architectures, new forms of DRAM and the emergence of new memory technologies that could enable the development of products that feature higher performance or lower cost. We may experience development, marketing and other technological difficulties that may delay or limit our ability to respond to technological changes, evolving industry standards, competitive developments or end-user requirements. For example, because we have limited experience developing integrated circuits, or IC, products other than Very Fast SRAMs, our efforts to introduce new products may not be successful and our business may suffer. Other challenges that we face include:

•: our products may become obsolete upon the introduction of alternative technologies;
•: we may incur substantial costs if we need to modify our products to respond to these alternative technologies;
•: we may not have sufficient resources to develop or acquire new technologies or to introduce new products capable of competing with future technologies;
•: new products that we develop may not successfully integrate with our end-users' products into which they are incorporated;
•: we may be unable to develop new products that incorporate emerging industry standards;
•: we may be unable to develop or acquire the rights to use the intellectual property necessary to implement new technologies; and
•: when introducing new or enhanced products, we may be unable to manage effectively the transition from older products.

Our products have lengthy sales cycles that make it difficult to plan our expenses and forecast results.

Our products are generally incorporated in our OEM customers' products at the design stage. However, their decisions to use our products often require significant expenditures by us without any assurance of success, and often precede volume sales, if any, by a year or more. If an OEM customer decides at the design stage not to incorporate our products into their products, we will not have another opportunity for a design win with respect to that customer's product for many months or years, if at all. Our sales cycle can take up to 24 months to complete, and because of this lengthy sales cycle, we may experience a delay between increasing expenses for research and development and our sales and marketing efforts and the generation of volume production revenues, if any, from these expenditures. Moreover, the value of any design win will largely depend on the commercial success of our OEM customers' products. There can be no assurance that we will continue to achieve design wins or that any design win will result in future revenues.

Any significant order cancellations or order deferrals could adversely affect our operating results.

We typically sell products pursuant to purchase orders that customers can generally cancel or defer on short notice without incurring a significant penalty. Any significant cancellations or deferrals in the future could materially and adversely affect our business, financial condition and results of operations. Cancellations or deferrals could cause us to hold excess inventory, which could reduce our profit margins, increase product obsolescence and restrict our ability to fund our operations. We generally recognize revenue upon shipment of products to a customer. If a customer refuses to accept shipped products or does not pay for these products, we could miss future revenue projections or incur significant charges against our income, which could materially and adversely affect our operating results.

We are subject to pending legal proceedings.

We have been named as a defendant in a number of civil antitrust complaints filed against semiconductor companies on behalf of purported classes of direct and indirect purchasers of SRAM products throughout the United States. The complaints allege that the defendants conspired to raise the price of SRAM in violation of Section 1 of the Sherman Act, the California Cartwright Act, and several other state antitrust, unfair competition and consumer protection statutes. We believe that we have meritorious defenses to the allegations in the complaints, and we intend to defend these lawsuits vigorously. However, the litigation is in the preliminary stage and we cannot predict its outcome. Multidistrict antitrust litigation is particularly complex and can extend for a protracted time, which can substantially increase the cost of such litigation. The defense of these lawsuits is also expected to divert the efforts and attention of some of our key management and technical personnel. As a result, our defense of this litigation, regardless of its eventual outcome, will likely be costly and time consuming. Should the outcome of the litigation be adverse to us, we could be required to pay significant monetary damages, which could adversely affect our business, financial condition, operating results and cash flows.

As our business grows, such growth may place a significant strain on our management and operations and, as a result, our business may suffer.

We plan to continue expanding our business, and our expected growth could place a significant strain on our management systems, infrastructure and other resources. To manage the expected growth of our operations and increases in the number of our personnel, we will need to invest the necessary capital to improve our operational, financial and management controls and our reporting systems and procedures. Accordingly, we are currently transitioning the preparation of all of our internal reporting to a new enterprise resource planning system, which is expected to be implemented in the first quarter of fiscal 2008. If we encounter problems with the implementation of this system, we may have

difficulties tracking internal information, which would adversely affect our ability to timely report our financial results. Our controls, systems and procedures might not be adequate to support a growing public company. In addition, we likely do not have sufficient administrative staff to support our operations. For example, we currently have only three employees in our finance department in the United States, including our Chief Financial Officer. Furthermore, our officers have limited experience in managing large or rapidly growing businesses and the majority of our management has no experience in managing a public company or communicating with securities analysts and public company investors. If our management fails to respond effectively to changes in our business, our business may suffer.

Our international business exposes us to additional risks.

Products shipped to destinations outside of the United States accounted for 51.9%, 48.3% and 49.4% of our net revenues in fiscal 2005 and 2006 and the nine months ended December 31, 2006, respectively. Moreover, a substantial portion of our products is manufactured and tested in Taiwan. We intend to expand our international business in the future. Conducting business outside of the United States subjects us to additional risks and challenges, including:

•: heightened price sensitivity from customers in emerging markets;
•: compliance with a wide variety of foreign laws and regulations;
•: legal uncertainties regarding taxes, tariffs, quotas, export controls, competition, export licenses and other trade barriers;
•: political and economic instability in, or foreign conflicts that involve or affect, the countries of our customers;
•: difficulties in collecting accounts receivable and longer accounts receivable payment cycles;
•: difficulties in staffing and managing personnel, distributors and representatives;
•: limited protection for intellectual property rights in some countries; and
•: fluctuations in freight rates and transportation disruptions.

Moreover, our reporting currency is the U.S. dollar. However, a portion of our cost of revenues and our operating expenses is denominated in currencies other than the U.S. dollar, primarily the New Taiwanese dollar. As a result, appreciation or depreciation of other currencies in relation to the U.S. dollar could result in transaction gains or losses that could impact our operating results. We do not currently engage in currency hedging activities.

TSMC, our other independent suppliers and many of our OEM customers have operations in the Pacific Rim, an area subject to significant earthquake risk and adverse consequences related to the potential outbreak of contagious diseases such as the Avian Flu.

The foundry that manufactures our products, TSMC, and all of the principal independent suppliers that assemble and test our products are located in Taiwan. Many of our customers are also located in the Pacific Rim. The risk of an earthquake in these Pacific Rim locations is significant. The occurrence of an earthquake or other natural disaster near the fabrication facilities of TSMC or our other independent suppliers could result in damage, power outages and other disruptions that impair their production and assembly capacity. Any disruption resulting from such events could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling, packaging or production testing from the affected contractor to another third-party vendor. In such an event, we may not be able to obtain alternate foundry capacity on favorable terms, or at all.

The outbreak of SARS in 2003 curtailed travel to and from certain countries, primarily in the Asia-Pacific region, and limited travel within those countries. If there were to be another outbreak of a

contagious disease, such as SARS or the Avian Flu, that significantly affected the Asia-Pacific region, the operations of our key suppliers could be disrupted. In addition, our business could be harmed if such an outbreak resulted in travel being restricted, as it was during parts of 2003, or if it adversely affected the operations of our OEM customers or the demand for our products or our OEM customers' products.

Changes in Taiwan's political, social and economic environment may affect our business performance.

Because much of the manufacturing and testing of our products is conducted in Taiwan, our business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage our business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies affecting technology companies, foreign investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on our ability and our suppliers' ability to do business and operate facilities in Taiwan. If any of these changes were to occur, our business could be harmed and our stock price could decline.

Market demand for our products may decrease as a result of changes in general economic conditions, as well as incidents of terrorism, war and other social and political instability.

Our revenues and gross profit depend largely on general economic conditions and, in particular, the strength of demand for our products in the markets in which we are doing business. From time to time, customers and potential customers have elected not to make purchases of our products due to reduced budgets and uncertainty about the future, and, in the case of distributors, declining demand from their customers for their solutions in which they integrate our products. Similarly, from time to time, acts of terrorism, in particular in the United States, have had a negative impact on information technology spending. High fuel prices and turmoil in the Middle East and elsewhere have increased uncertainty in the United States and our other markets. Should the current conflicts in the Middle East and in other parts of the world suppress economic activity in the United States or globally, our customers may delay or reduce their purchases on information technology, which would result in lower demand for our products and adversely affect our results of operations.

We are substantially dependent on the continued services and performance of our senior management and other key personnel.

Our future success is substantially dependent on the continued services and continuing contributions of our senior management who must work together effectively in order to design our products, expand our business, increase our revenues and improve our operating results. The loss of services of Lee-Lean Shu, our President and Chief Executive Officer, Robert Yau, our Vice President of Engineering, any other executive officer or other key employee could significantly delay or prevent the achievement of our development and strategic objectives. We do not have employment contracts with, nor maintain key person insurance on, any of our executive officers.

If we are unable to recruit or retain qualified personnel, our business and product development efforts could be harmed.

We must continue to identify, recruit, hire, train, retain and motivate highly skilled technical, managerial, sales and marketing and administrative personnel. Competition for these individuals is intense, and we may not be able to successfully recruit, assimilate or retain sufficiently qualified personnel. We may encounter difficulties in recruiting and retaining a sufficient number of qualified engineers, which could harm our ability to develop new products and adversely impact our relationships with existing and future end-users at a critical stage of development. The failure to recruit and retain

necessary technical, managerial, sales, marketing and administrative personnel could harm our business and our ability to obtain new OEM customers and develop new products.

We may need to raise additional capital in the future, which may not be available on favorable terms or at all, and which may cause dilution to existing stockholders.

We may need to seek additional funding in the future. We do not know if we will be able to obtain additional financing on favorable terms, if at all. If we cannot raise funds on acceptable terms, if and when needed, we may not be able to develop or enhance our products, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, and we may be required to reduce operating costs, which could seriously harm our business. In addition, if we issue equity securities, our stockholders may experience additional dilution or the new equity securities may have rights, preferences or privileges senior to those of our common stock.

Our products are increasingly being incorporated into advanced military electronics, and changes in international geopolitical circumstances and domestic budget considerations may hurt our business.

Our products are increasingly being incorporated into advanced military electronics such as radar and guidance systems. Military expenditures and appropriations for such purchases have risen significantly in recent years. However, should the current conflicts in Iraq and Afghanistan and the general war on terror subside, our operating results would likely suffer. Domestic budget considerations may also adversely affect our operating results. For example, if governmental appropriations for military purchases of electronic devices that include our products are reduced, our revenues will likely decline.

If we acquire any companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our operating results.

In the future, we may acquire or make investments in companies, assets or technologies that we believe are complementary or strategic. We have not made any acquisitions or investments to date, and therefore our ability as an organization to make acquisitions or investments is unproven. If we decide to make an acquisition or investment, we face numerous risks, including:

•: difficulties in integrating operations, technologies, products and personnel;
•: diversion of financial and managerial resources from existing operations;
•: risk of overpaying for or misjudging the strategic fit of an acquired company, asset or technology;
•: problems or liabilities stemming from defects of an acquired product or intellectual property litigation that may result from offering the acquired product in our markets;
•: challenges in retaining employees key to maximize the value of the acquisition or investment;
•: inability to generate sufficient return on investment;
•: incurrence of significant one-time write-offs; and
•: delays in customer purchases due to uncertainty.

If we proceed with an acquisition or investment, we may be required to use a considerable amount of our cash, including proceeds from this offering, or to finance the transaction through debt or equity securities offerings, which may decrease our financial liquidity or dilute our stockholders and affect the market price of our stock. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be harmed.

Maintaining and improving our financial controls and complying with rules and regulations applicable to public companies will be a significant burden on our management team and require considerable expenditures of our resources.

As a public company, we will incur additional legal, accounting and other expenses that we do not incur as a private company. The Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and The Nasdaq Marketplace Rules, or Nasdaq rules, will apply to us as a public company. Compliance with these rules and regulations will necessitate significant increases in our legal and financial budgets and may also strain our personnel, systems and resources.

The Exchange Act requires, among other things, filing of annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. Satisfying these requirements involves a commitment of significant resources and management oversight. As a result of management's efforts to comply with such requirements, other important business concerns may receive insufficient attention, which could have a material adverse effect on our business, financial condition and results of operations. Failure to meet certain of these regulatory requirements may also cause us to be delisted from the Nasdaq Global Market.

In addition, in order to comply with these additional requirements, we are hiring and will continue to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge, which will increase our operating expenses in future periods.

We also expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to maintain coverage. If we are unable to maintain adequate directors' and officers' insurance, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors, particularly to serve on our audit committee, and qualified executive officers.

Our operations involve the use of hazardous and toxic materials, and we must comply with environmental laws and regulations, which can be expensive, and may affect our business and operating results.

We are subject to federal, state and local regulations relating to the use, handling, storage, disposal and human exposure to hazardous and toxic materials. If we were to violate or become liable under environmental laws in the future as a result of our inability to obtain permits, human error, accident, equipment failure or other causes, we could be subject to fines, costs, or civil or criminal sanctions, face property damage or personal injury claims or be required to incur substantial investigation or remediation costs, which could be material, or experience disruptions in our operations, any of which could have a material adverse effect on our business. In addition, environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business.

We also face increasing complexity in our product design as we adjust to new and future requirements relating to the materials composition of our products, including the restrictions on lead and other hazardous substances applicable to specified electronic products placed on the market in the European Union (Restriction on the Use of Hazardous Substances Directive 2002/95/EC, also known as the RoHS Directive). We also expect that our operations will be affected by other new environmental laws and regulations on an ongoing basis. Although we cannot predict the ultimate impact of any such new laws and regulations, they will likely result in additional costs, and could require that we change the design and/or manufacturing of our products, any of which could have a material adverse effect on our business.

Risks Related to this Offering and Our Common Stock

There has been no prior market for our common stock and the price of our common stock may decline after this offering.

Before this offering, there has not been a public market for our common stock and the trading price of our common stock may decline below the initial public offering price. The initial public offering price has been determined by negotiations between us and the representatives of the underwriters and may not be indicative of prices that will prevail in the trading market.

An active trading market may not develop and you may not be able to resell the shares you purchase at or above the initial public offering price, or at all. The trading price of our common stock may fluctuate significantly in response to a number of factors, some of which are beyond our control, including:

•: actual or anticipated declines in operating results;
•: changes in financial estimates or recommendations by securities analysts;
•: announcements by us or our competitors of financial results, new products, significant technological innovations, contracts, acquisitions, strategic relationships, joint ventures, capital commitments or other events;
•: rapid changes in industry estimates in demand for Very Fast SRAM products;
•: the gain or loss of significant orders or customers;
•: recruitment or departure of key personnel; and
•: market conditions in our industry, the industries of our customers and the economy as a whole.

If securities analysts do not publish research or reports about our business, our stock price could decline.

The trading market for our common stock will rely in part on the research and reports that industry or financial analysts publish about us or our business. Other companies in our industry and market are larger, established, publicly traded companies. As a result, it may be difficult for us to attract analyst coverage. If we should be unable to attract analyst coverage or if one or more of these analysts should cease coverage of our company, our visibility in the financial market would suffer, which in turn could cause our stock price to decline. Furthermore, if one or more of the analysts who cover us downgrade our stock, our stock price would likely decline rapidly.

The price of our stock may be volatile, which could harm our business or stockholders and result in litigation.

In recent years the stock market in general, and the market for technology stocks in particular, have experienced extreme price fluctuations, which have often been unrelated to the operating performance of affected companies. The market price of our common stock might experience significant fluctuations in the future, including fluctuations unrelated to our performance. These fluctuations could materially adversely affect our business relationships, our ability to obtain future financing on favorable terms or otherwise harm our business. In addition, in the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. This risk is especially acute for us because the extreme volatility of market prices of technology companies has resulted in a larger number of securities class action claims against them. Due to the potential volatility of our stock price, we may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management's attention and resources. This could harm our business and cause the value of our stock to decline.

We have no specific plan for the use of the net proceeds, and our investment of the net proceeds may not yield a favorable return.

We plan to use most of the net proceeds from this offering for general corporate purposes, including working capital. We may use the net proceeds in ways with which our stockholders may not agree or that prove to be disadvantageous to our stockholders. We may not be able to invest the net proceeds of this offering in a manner that yields a favorable return, which could harm our financial position and cause the value of our stock to decline.

After this offering we will continue to be controlled by our executive officers, directors and major stockholders, whose interests may conflict with yours.

Upon completion of this offering, our executive officers, directors and major stockholders will beneficially own approximately 65.6% of our outstanding common stock. As a result, these stockholders will be able to exercise control over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could have the effect of delaying or preventing a third party from acquiring control over or merging with us.

The provisions of our charter documents might inhibit potential acquisition bids that a stockholder might believe are desirable, and the market price of our common stock could be lower as a result.

Upon completion of this offering, our Board of Directors will have the authority to issue up to 5,000,000 shares of preferred stock. Our Board of Directors can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock might delay or prevent a change in control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders might be adversely affected. The issuance of preferred stock might result in the loss of voting control to other stockholders. We have no current plans to issue any shares of preferred stock. Our charter documents also contain other provisions, which might discourage, delay or prevent a merger or acquisition, including:

•: our stockholders have no right to remove directors without cause;
•: our stockholders have no right to act by written consent;
•: our stockholders have no right to call a special meeting of stockholders; and
•: stockholders must comply with advance notice requirements to nominate directors or submit proposals for consideration at stockholder meetings.

These provisions could also have the effect of discouraging others from making tender offers for our common stock. As a result, these provisions might prevent the market price of our common stock from increasing substantially in response to actual or rumored takeover attempts. These provisions might also prevent changes in our management.

You will experience immediate and substantial dilution in the book value of your shares.

The initial public offering price of our common stock is substantially higher than the book value per share of our outstanding common stock immediately after the offering. Accordingly, if you purchase common stock in the offering, you will incur immediate dilution of approximately $3.07 in the book value of our common stock at the initial public offering price of $5.50 per share, based on pro forma net tangible book value as of December 31, 2006.

You will experience additional dilution upon the exercise of outstanding options. As of December 31, 2006, there were 4,348,869 shares issuable upon the exercise of outstanding options with a weighted average exercise price of $3.52. In addition, you may experience dilution upon the exercise

of options that may be granted in the future. We have reserved an aggregate of 3,500,000 shares for future issuance under our 2007 equity incentive plan and 2007 employee stock purchase plan.

There are a large number of shares of our common stock that may be sold in the market following this offering, which may depress the market price of our common stock.

The market price of our common stock could decline as a result of sales of substantial amounts of our common stock in the public market after the completion of this offering, or the perception that those sales could occur. These sales or the possibility that they may occur also could make it more difficult for us to raise funds through future offerings of common stock. The number of shares of common stock available for sale in the public market is limited by restrictions under federal securities laws. In addition, we and the holders of approximately 99% of our common stock, including all of our executive officers and directors, have agreed not to sell shares of our common stock without the consent of the underwriters for 180 days after the day of this prospectus. The joint book-running managers may, however, in their sole discretion and without notice, release all or any portion of the shares from the restrictions in these lock-up agreements.

Shares of our common stock will become eligible for future sale in the public market as follows:

Number of Shares		Date Eligible
221,561		immediately as of the date of this prospectus
21,181,268		180 days after the date of this prospectus, upon expiration of the lock-up agreements

We intend to register on a Form S-8 registration statement under the Securities Act of 1933 a total of approximately 3,500,000 shares of common stock reserved for issuance under our stock option and employee stock purchase plans. As of December 31, 2006, there were outstanding options to purchase 4,348,869 shares of common stock, of which options to purchase 2,920,999 shares were vested and exercisable.

We do not expect to pay any cash dividends for the foreseeable future.

We do not anticipate that we will pay any cash dividends to holders of our common stock in the foreseeable future. Our credit line with Mega International Commercial Bank Co., Ltd., prohibits us from paying any cash dividend without the consent of that bank. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.

USE OF PROCEEDS

At the initial public offering price of $5.50 per share, we will receive approximately $30.2 million from our sale of 6,131,111 shares of common stock in this offering, after deducting the underwriting discount and estimated offering expenses of approximately $1.2 million, that includes $30,000 of estimated offering expenses payable by us on behalf of the selling stockholders. If the underwriters exercise their over-allotment option in full, the selling stockholders will receive approximately $4.7 million from their sale of 919,667 shares of our common stock, after deducting the underwriting discount. We will not receive any portion of the net proceeds from the sale of any shares that may be sold by the selling stockholders upon exercise of the underwriters' over-allotment option.

The principal purposes of this offering are to obtain additional capital, establish a public market for our common stock and facilitate our future access to public capital markets. We intend to use the net proceeds of this offering for working capital and other general corporate purposes, including capital expenditures and research and development. We may use a portion of the net proceeds to acquire businesses, products or technologies that are complementary to our current or future business and product lines; however, we have never made an acquisition and currently have no specific acquisitions planned. Our management will have significant flexibility in applying the net proceeds of this offering. Pending such uses, we will invest the net proceeds of this offering in investment grade, interest-bearing securities.

DIVIDEND POLICY

We have never declared or paid cash dividends on our common stock. We currently intend to retain future earnings to finance the growth and development of our business, and we do not anticipate declaring or paying any cash dividends in the foreseeable future. Our line of credit with Mega International Commercial Bank Co., Ltd. prohibits us from paying cash dividends without the consent of that bank.

CAPITALIZATION

The following table sets forth our capitalization as of December 31, 2006:

•: on an actual basis;
•: on a pro forma basis, giving effect to the conversion of all outstanding shares of our redeemable convertible preferred stock into 15,120,168 shares of common stock; and
•: on a pro forma basis as adjusted to reflect the sale of 6,131,111 shares of common stock by us in this offering, at the initial public offering price of $5.50 per share and after deducting the underwriting discount and estimated offering expenses payable by us, including offering expenses payable by us on behalf of the selling stockholders.

This capitalization table should be read together with "Selected Consolidated Financial Data" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and related notes included elsewhere in this prospectus.

(1): In connection with the offering, our estimated offering expenses are $1,150,000, which will be recorded as an issuance cost and, therefore, will be recorded as a reduction in additional paid in capital. We will also pay approximately $30,000 representing incremental expenses attributable to the selling stockholders, which will be expensed, thereby reducing retained earnings.

The information above excludes:

•: 4,348,869 shares issuable upon the exercise of options outstanding as of December 31, 2006 under our 1997 and 2000 stock option plans, with a weighted average exercise price of $3.52 per share;
•: 559,897 shares authorized for future issuance under our 2000 stock option plan;
•: 3,000,000 shares authorized for future issuance under our 2007 equity incentive plan; and

•: 500,000 shares authorized for future issuance under our 2007 employee stock purchase plan.

The number of shares authorized for future issuance under our 2007 equity incentive plan and 2007 employee stock purchase plan reflected above does not include shares that may be available for future issuance pursuant to the automatic share reserve increase provisions of these plans. The share reserve for our 2007 equity incentive plan will automatically increase on April 1 of each year, from 2008 to 2017, by an amount equal to the lesser of (a) five percent of the number of shares issued and outstanding as of the immediately preceding March 31, or (b) a lesser amount determined by the Board. The share reserve for our 2007 employee stock purchase plan will automatically increase on April 1 of each year, from 2008 to 2017, by an amount equal to the lesser of (x) one percent of the number of shares issued and outstanding as of the immediately preceding March 31, or (y) 250,000 shares.

DILUTION

Purchasers of our common stock in this offering will experience immediate and substantial dilution in the pro forma net tangible book value of their common stock. The pro forma net tangible book value of our common stock as of December 31, 2006 was $36.8 million, or $1.72 per share. Pro forma net tangible book value per share represents the amount of our total assets, excluding net intangible assets, less our total liabilities, divided by the total number of shares of common stock outstanding, after giving effect to the conversion of all outstanding shares of redeemable convertible preferred stock into an aggregate of 15,120,168 shares of common stock. Dilution in pro forma net tangible book value per share represents the difference between the amount per share paid by investors in this offering and the pro forma net tangible book value per share of our common stock immediately after the offering. After giving effect to our sale of 6,131,111 shares of common stock in this offering, at the initial public offering price of $5.50 per share, and after deducting the underwriting discount and estimated offering expenses payable by us, the pro forma net tangible book value of our common stock would have been $67.0 million, or $2.43 per share. This represents an immediate increase in net tangible book value of $0.71 per share to existing stockholders and an immediate dilution of $3.07 per share to new investors. The following table illustrates this per share dilution:

Initial public offering price				$	5.50
	Pro forma net tangible book value per share as of December 31, 2006	$	1.72
	Increase in pro forma net tangible book value per share attributable to this offering		0.71

Pro forma as adjusted net tangible book value per share after the offering					2.43

Dilution to new public investors				$	3.07

The following table summarizes, on a pro forma as adjusted basis, as of December 31, 2006:

•: the number of shares of common stock purchased from us;
•: the total consideration paid to us;
•: the average price per share paid by existing stockholders; and
•: the price per share paid by new investors in this offering at the initial public offering price of $5.50, before deducting the underwriting discount and estimated offering expenses payable by us.

		Shares Purchased			Total Consideration
		Shares Purchased			Total Consideration				Average Price Per Share
		Number	Percent		Amount		Percent		Average Price Per Share
Existing stockholders(1)		21,402,829	77.7	%	$	9,556,952	22.1	%	$	0.45
New investors(1)		6,131,111	22.3			33,721,111	77.9			5.50

	Total	27,533,940	100.0	%	$	43,278,063	100.0	%

(1): In the event that the underwriters exercise their over-allotment option in full, sales by the selling stockholders in this offering will reduce the number of shares held by existing stockholders to 20,483,162, or 74.4% of the total number of shares of common stock outstanding after this offering, and will increase the number of shares to be purchased by the new public investors to 7,050,778, or 25.6% of the total number of shares of common stock outstanding after the offering. See "Principal and Selling Stockholders."

The information in the above table excludes 4,348,869 shares issuable upon exercise of options outstanding at December 31, 2006 under our 1997 and our 2000 stock option plans, with a weighted average exercise price of $3.52 per share. To the extent these options are exercised, there will be

further dilution to the new investors. Assuming the exercise of all outstanding options as of December 31, 2006:

•: the pro forma as adjusted net tangible book value of our common stock would have been $2.58 per share, representing an immediate dilution of $2.92 per share to new investors;
•: the number of shares purchased by existing stockholders would have been 25,751,698;
•: the total consideration paid by existing stockholders would have been $24.9 million; and
•: the average price per share paid by existing stockholders would have been $0.97.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ substantially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under "Risk Factors" and elsewhere in this prospectus. The following discussion should be read together with our consolidated financial statements and the related notes included elsewhere in this prospectus.

Overview

We are a fabless semiconductor company that designs, develops and markets Very Fast SRAMs primarily for the networking and telecommunications markets. We were founded in March 1995 to develop SRAMs then targeted principally at the personal computer, or PC, market. We shipped our first products in commercial volumes in fiscal 1998. During that year, we changed our focus from marketing commodity SRAMs in the highly competitive PC market to developing and marketing advanced Very Fast SRAMs for the networking and telecommunications markets. Subsequent to fiscal 1998, product sales in these markets have represented approximately 70% to 90% of our net revenues. We are subject to the highly cyclical nature of the semiconductor industry, which has experienced significant fluctuations, often in connection with fluctuations in demand for the products in which semiconductor devices are used. Beginning in fiscal 2001, the networking and telecommunications markets experienced an extended period of severe contraction, during which our operating results sharply declined. Between fiscal 2004 and fiscal 2006, demand for networking and telecommunications equipment recovered. In recent quarters, demand for such equipment has accelerated and, as a result, our operating results have improved.

Revenues. Our revenues are derived primarily from sales of our Very Fast SRAM products. Sales to networking and telecommunications OEMs accounted for 70% to 80% of our net revenues during our last three fiscal years. We also sell our products to OEMs that manufacture products for defense applications such as radar and guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control and voice recognition systems, and for medical applications such as ultrasound and CAT scan equipment. As is typical in the semiconductor industry, the selling prices of our products generally decline over the life of the product. Our ability to increase net revenues, therefore, is dependent upon our ability to increase unit sales volumes of existing products and to introduce and sell new products with higher average selling prices in quantities sufficient to compensate for the anticipated declines in selling prices of our more mature products. Although we expect the average selling prices of individual products to decline over time, we believe that, over the next several quarters, our overall average selling prices will increase due to a continuing shift in product mix to a higher percentage of higher price, higher density products. Our ability to increase unit sales volumes is dependent primarily upon increases in customer demand but, particularly in periods of increasing demand, can also be affected by our ability to increase production through the availability of increased wafer fabrication capacity from TSMC, our wafer supplier, and our ability to increase the number of good integrated circuit die produced from each wafer through die size reductions and yield enhancement activities.

We may experience fluctuations in quarterly net revenues for a number of reasons. Historically, orders on hand at the beginning of each quarter are insufficient to meet our revenue objectives for that quarter and are generally cancelable up to 30 days prior to scheduled delivery. Accordingly, we depend on obtaining and shipping orders in the same quarter to achieve our revenue objectives. In addition, the timing of product releases, purchase orders and product availability could result in significant product shipments at the end of a quarter. Failure to ship these products by the end of the quarter may

adversely affect our operating results. Furthermore, we typically provide that customers may delay scheduled delivery dates and cancel orders within specified time frames without significant penalty.

We sell our products through our direct sales force, international and domestic sales representatives and distributors. Revenues from product sales, except for sales to distributors, are generally recognized upon shipment, net of sales returns and allowances. Sales to consignment warehouses, who purchase products from us for use by contract manufacturers, are recorded upon delivery to the contract manufacturer. Sales to distributors are recorded as deferred revenues for financial reporting purposes and recognized as revenues when the products are resold by the distributors to the OEM.

Historically, a small number of OEM customers have accounted for a substantial portion of our net revenues, and we expect that significant customer concentration will continue for the foreseeable future. Many of our OEMs use contract manufacturers to manufacture their equipment. Accordingly, a significant percentage of our net revenues is derived from sales to these contract manufacturers and to consignment warehouses. In addition, a significant portion of our sales are made to foreign and domestic distributors who resell our products to OEMs, as well as their contract manufacturers. Direct sales to contract manufacturers and consignment warehouses accounted for 38.8%, 38.8%, 35.0%, 34.6% and 36.4% of our net revenues for fiscal 2004, 2005 and 2006 and the nine months ended December 31, 2005 and 2006, respectively. Sales to foreign and domestic distributors accounted for 46.8%, 49.7%, 55.7%, 56.5% and 56.5% of our net revenues for fiscal 2004, 2005 and 2006 and the nine months ended December 31, 2005 and 2006, respectively. The following direct customers accounted for 10% or more of our net revenues in one or more of the following periods:

		Fiscal Year Ended March 31,						Nine Months Ended December 31,
		2004		2005		2006		2005		2006
Consignment warehouses:
	SMART Modular Technologies	27.1	%	31.8	%	27.3	%	27.4	%	31.3	%
Distributors:
	Avnet Logistics	32.0		32.5		30.4		32.7		24.2
	Nu Horizons	3.0		6.1		10.3		9.4		8.4

Cisco Systems, our largest OEM customer, purchases our products primarily through its consignment warehouse, SMART Modular Technologies, and also purchases some products through its contract manufacturers and directly from us. Cisco Systems is one of two of our OEM customers that purchase our products through a consignment warehouse. Historically, purchases by Cisco Systems have fluctuated from period to period. Based on information provided to us by Cisco Systems' consignment warehouse and contract manufacturers, purchases by Cisco Systems represented approximately 31%, 34%, 28% and 32% of our net revenues in fiscal 2004, 2005 and 2006 and the nine months ended December 31, 2006, respectively. We expect Cisco Systems to account for a lesser percentage of our net revenues for the quarter ending March 31, 2007. Cisco Systems has announced the implementation of a "lean manufacturing" program under which it plans to reduce the levels of inventory carried by it and by its contract manufacturers. We believe that the transition to this new program will result in reductions in purchases of our products by Cisco Systems' contract manufacturers during the quarter ending March 31, 2007, as they draw down their existing inventories, and that such reductions will likely result in our net revenues for the quarter being less than in the previous quarter. This transition could also impact our revenues in the quarter ending June 30, 2007.

To our knowledge, none of our other OEM customers accounted for more than 10% of our net revenues during any of these periods.

Cost of Revenues. Our cost of revenues consists primarily of wafer fabrication costs, wafer sort, assembly, test and burn-in expenses, the amortized cost of production mask sets, and the cost of materials and overhead from operations. All of our wafer manufacturing and assembly operations, and most of our product testing operations, are outsourced. Accordingly, most of our cost of revenues consists of payments to TSMC and independent assembly and test houses. Because we do not have long-term, fixed-price supply contracts, our wafer fabrication and other outsourced manufacturing costs are subject to the cyclical fluctuations in demand for semiconductors. Cost of revenues also includes expenses related to supply chain management, quality assurance, and final product testing and documentation control activities conducted at our headquarters in Santa Clara, California and our branch operations in Taiwan.

Gross Profit. Our gross profit margins vary among our products and are generally greater on our higher density products and, within a particular density, greater on our higher speed and industrial temperature products. We expect that our overall gross margins will fluctuate from period to period as a result of shifts in product mix, changes in average selling prices and our ability to control our cost of revenues, including costs associated with outsourced wafer fabrication and product assembly and testing.

Research and Development Expenses. Research and development expenses consist primarily of salaries and related expenses for design engineers and other technical personnel, the cost of developing prototypes, stock-based compensation and fees paid to consultants. We charge all research and development expenses to operations as incurred. We charge mask costs used in production to costs of revenues over a 12-month period. However, we charge costs related to pre-production mask sets, which are not used in production, to research and development expenses at the time they are incurred. These charges often arise as we transition to new process technologies and, accordingly, can cause research and development expenses to fluctuate on a quarterly basis. We believe that continued investment in research and development is critical to our long-term success, and we expect to continue to devote significant resources to product development activities. Accordingly, we expect that our research and development expenses will increase in future periods, although such expenses as a percentage of net revenues may fluctuate.

Selling, General and Administrative Expenses. Selling, general and administrative expenses consist primarily of commissions paid to independent sales representatives, salaries, stock-based compensation and related expenses for personnel engaged in sales, marketing, administrative, finance and human resources activities, professional fees, costs associated with the promotion of our products and other corporate expenses. We expect that our sales and marketing expenses will increase in absolute dollars in future periods as we continue to grow and expand our sales force but that, to the extent our revenues increase in future periods, these expenses will generally decline as a percentage of net revenues. We also expect that, in support of our continued growth and our operations as a public company, general and administrative expenses will continue to increase in absolute dollars for the foreseeable future but will fluctuate as a percentage of net revenues.

Provision for (Benefit from) Income Taxes. We incurred operating losses in each of the fiscal years ended March 31, 2002, March 31, 2003 and March 31, 2004. Due to operating losses incurred in fiscal 2002 and fiscal 2003, we established a full valuation allowance in fiscal 2003 for deferred tax assets. This valuation allowance was based on our assessment that realization of deferred tax assets was uncertain due to our recent history of operating losses and our inability to conclude that it was more likely than not that sufficient taxable income would be generated in future periods to realize those deferred tax assets.

Nine Months Ended December 31, 2006 Compared to Nine Months Ended December 31, 2005

Net Revenues. Net revenues increased by 35.0% from $32.7 million in the nine months ended December 31, 2005 to $44.2 million in the nine months ended December 31, 2006. This increase was primarily due to an 8.3% increase in unit sales as a result of increased demand from our networking and telecommunications OEMs. Unit sales increased across our product lines, particularly for our 18 and 36 megabit Very Fast SRAM products. Net revenues also improved as a result of a 22.0% increase in the overall average selling price of our products due to a shift in product mix to a larger percentage of higher price, higher density products. We believe that OEM demand increased largely as a result of a general improvement in the business environment and an increase in capital expenditures for networking and telecommunications equipment.

Cost of Revenues. Cost of revenues increased by 19.2% from $22.8 million in the nine months ended December 31, 2005 to $27.2 million in the nine months ended December 31, 2006. This increase was primarily due to the 8.3% increase in unit shipments and a shift in product mix to higher cost, higher density products, partially offset by various cost reduction measures, including the negotiation of price reductions for wafers purchased from TSMC and for assembly and test services provided by our contractors.

Cost of revenues included stock-based compensation of $10,000 and $154,000 for the nine months ended December 31, 2005 and 2006, respectively.

Gross Profit. Gross profit increased by 71.2% from $9.9 million in the nine months ended December 31, 2005 to $17.0 million in the nine months ended December 31, 2006. Gross margin increased from 30.3% in the nine months ended December 31, 2005 to 38.4% in the nine months ended December 31, 2006. This increase in gross margin was primarily related to the shift in product mix. The cost reduction measures described above also contributed to the improvement in gross margin.

Research and Development Expenses. Research and development expenses decreased 10.4% from $4.2 million in the nine months ended December 31, 2005 to $3.8 million in the nine months ended December 31, 2006. This decrease was primarily due to $678,000 in costs incurred in September 2005 for pre-production mask sets related to the transition to our new 90 nanometer process technology. The decrease was partially offset by increases of $139,000 in other prototype expenses and $50,000 in outside design consultant expenses.

Research and development expenses included stock-based compensation expense of $53,000 and $371,000 for the nine months ended December 31, 2005 and 2006, respectively.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased 24.3% from $3.6 million in the nine months ended December 31, 2005 to $4.4 million in the nine months ended December 31, 2006. This increase was primarily related to an increase of $336,000 in commissions paid to manufacturers' representatives resulting from the increase in net revenues and an increase of $134,000 in payroll related expenses.

Selling, general and administrative expenses included stock-based compensation expense of $9,000 and $284,000 for the nine months ended December 31, 2005 and 2006, respectively.

Interest and Other Income (Expense), Net. Interest and other income (expense), net increased by 36.6%, from $396,000 in the nine months ended December 31, 2006 to $541,000 in the nine months ended December 31, 2006. This increase was primarily the result of an increase in interest income of $287,000 due to higher interest rates and higher average balances of invested cash, offset in part by a foreign exchange loss related to our Taiwan branch operations.

Provision for (Benefit from) Income Taxes. The provision for income taxes increased from a benefit of $401,000 in the nine months ended December 31, 2005 to an expense of $3.3 million in the nine months ended December 31, 2006. This increase was due to the increase in pre-tax income and the release of $895,000 of tax reserves in 2005 following the conclusion of an income tax audit by the Internal Revenue Service.

Net Income. Net income increased 104.6% from $2.9 million in the nine months ended December 31, 2005 to $6.0 million in the nine months ended December 31, 2006. This increase was primarily due to increased net revenues and improved gross margins.

Fiscal Year Ended March 31, 2006 Compared to Fiscal Year Ended March 31, 2005

Net Revenues. Net revenues decreased by 5.7% from $45.7 million in fiscal 2005 to $43.1 million in fiscal 2006. This decrease was primarily due to an 18.9% decrease in unit sales, partially offset by an increase of 15.3% in the overall average selling price of our products due to a shift in product mix to a larger percentage of higher price, higher density products. Revenue growth during fiscal 2006 was adversely impacted by our inability to ship certain of our 36 megabit products due to an error in the assembly process at one of our suppliers.

Cost of Revenues. Cost of revenues decreased by 4.8% from $30.7 million in fiscal 2005 to $29.2 million in fiscal 2006. This decrease was primarily due to the 18.9% decrease in unit shipments and a decrease in unit cost due to various cost reduction measures, including the negotiation of price reductions for wafers purchased from TSMC and for assembly and test services provided by our contractors. Offsetting these reductions was a charge of approximately $900,000 in fiscal 2006 related to the write-off of inventory resulting from the assembly error cited above.

Gross Profit. Gross profit decreased by 7.4% from $15.0 million in fiscal 2005 to $13.9 million in fiscal 2006 primarily due to the 5.7% decline in net revenues. Gross margin decreased from 32.8% in fiscal 2005 to 32.3% in fiscal 2006. This decrease in gross margin was primarily related to the write-off

of inventory resulting from the assembly error cited above. The decrease in gross margin was partially offset by the shift in product mix and the cost reduction measures described above.

Research and Development Expenses. Research and development expenses increased by 11.9% from $4.8 million in fiscal 2005 to $5.4 million in fiscal 2006. This increase was primarily due to $678,000 in costs incurred in fiscal 2006 for pre-production mask sets related to the transition to our new 90 nanometer process technology. The increase was partially offset by a decrease of $85,000 in payroll related expenses.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased by 16.7% from $5.8 million in fiscal 2005 to $4.8 million for fiscal 2006. This decrease was primarily related to the write-off in fiscal 2005 of $962,000 in costs incurred in 2004 in connection with a planned initial public offering of our common stock, which was not consummated, and a decrease in commissions paid to manufacturers' representatives, partially offset by increased payroll related expenses.

Interest and Other Income (Expense), Net. Interest and other income (expense), net increased by 315.9% from $164,000 in fiscal 2005 to $682,000 in fiscal 2006. Net interest earned on invested cash balances increased from $166,000 to $482,000 due to an increase in average cash balances and higher interest rates. In addition, foreign exchange gains related to our Taiwan branch operations increased from $6,000 in fiscal 2005 to $207,000 in fiscal 2006.

Provision for (Benefit from) Income Taxes. There was a $155,000 benefit from income taxes in fiscal 2005 compared to a tax expense of $171,000 in fiscal 2006. The income tax benefit in fiscal 2005 resulted from the release of our $1.7 million deferred tax valuation allowance. During fiscal 2005, we determined that there was sufficient positive evidence, including a recent history of generating taxable income, to release the deferred tax asset valuation allowance that was recorded as of March 31, 2004. The tax provision in fiscal 2006 reflects the release of $895,000 of tax reserves following the conclusion of an income tax audit by the Internal Revenue Service.

Net Income. Net income decreased by 11.1% from $4.8 million in fiscal 2005 to $4.2 million in fiscal 2006. This decrease was primarily due to decreased gross margins on reduced net revenues.

Fiscal Year Ended March 31, 2005 Compared to Fiscal Year Ended March 31, 2004

Net Revenues. Net revenues increased by 29.1% from $35.4 million in fiscal 2004 to $45.7 million in fiscal 2005. This increase was primarily due to a 13.0% increase in unit sales as a result of increased demand from our networking and telecommunications OEMs and an increase of 12.9% in the overall average selling price of our products due to a shift in product mix to a larger percentage of higher price, higher density products. We believe that OEM demand increased largely as a result of a general improvement in the business environment and an increase in capital expenditures for networking and telecommunications equipment.

Cost of Revenues. Cost of revenues increased 15.4% from $26.6 million in fiscal 2004 to $30.7 million in fiscal 2005. This increase was the result of the 13.0% increase in unit shipments and a shift in product mix to higher cost, higher density products. In addition, various cost reduction measures, which included the negotiation of price reductions for wafers purchased from TSMC and for assembly and test services provided by our contractors, helped reduce our product cost in fiscal 2005.

Gross Profit. Gross profit increased by 70.7% from $8.8 million in fiscal 2004 to $15.0 million in fiscal 2005. Gross margin increased from 24.8% in fiscal 2004 to 32.8% in fiscal 2005. This gross margin improvement was a result of the shift in product mix, with a greater proportion of revenues being generated by our higher margin, higher density products, lower costs as a result of the cost reduction measures described above, and reduced product cost due to yield improvement.

Research and Development Expenses. Research and development expenses decreased by 12.7% from $5.5 million in fiscal 2004 to $4.8 million in fiscal 2005. This decrease was primarily due to a $377,000 decrease in prototyping expenses and pre-production mask costs, a $300,000 decrease in stock-based compensation expense, a $124,000 decrease in depreciation expense and a $69,000 decrease in outside design consultant expense, partially offset by an increase of $189,000 in payroll related expenses.

Selling, General and Administrative Expenses. Selling, general and administrative expenses increased by 38.6% from $4.2 million in fiscal 2004 to $5.8 million in fiscal 2005. This increase was primarily due to the write-off in fiscal 2005 of $962,000 of costs incurred in 2004 in connection with a planned initial public offering of our common stock, which was not consummated, an increase of $307,000 in commissions paid to manufacturers' representatives as a result of increased net revenues, an increase of $170,000 in payroll related expenses, and an increase of $167,000 in professional fees.

Interest and Other Income (Expense), Net. Interest and other income (expense), net decreased by 9.9% from $182,000 in fiscal 2004 to $164,000 in fiscal 2005. This decrease resulted from reductions in our average cash balances and fluctuating foreign exchange rates that impacted our operations in Taiwan.

Provision for (Benefit from) Income Taxes. There was no tax provision in fiscal 2004 due to our pre-tax loss. The $155,000 benefit from income taxes in fiscal 2005 resulted from the release of our deferred tax valuation allowance. During fiscal 2005, we determined that there was sufficient positive evidence, including a recent history of generating taxable income, to release the deferred tax asset valuation allowance that was recorded as of March 31, 2004. Accordingly, we released the deferred tax valuation allowance of $1.7 million during fiscal 2005.

Net Income (Loss). Net income increased to $4.8 million in fiscal 2005 from a loss of $670,000 in fiscal 2004. This increase was primarily due to the increases in net revenues and gross margin.

Net Revenues. Net revenues fluctuated between $10.4 million and $11.2 million over the four quarters ended March 31, 2006, and then grew to $14.0 million, $15.0 million and $15.3 million in the quarters ended June 30, 2006, September 30, 2006 and December 31, 2006, respectively, primarily due to increases in unit sales as a result of increased demand from our networking and telecommunications OEMs and generally increasing overall average selling prices.

Gross Profit. Gross profit margins fluctuated over the seven quarter period ended December 31, 2006. During the five quarters ended June 30, 2006, gross margins improved on a quarterly basis from 32.1% in the quarter ended June 30, 2005 to 39.9% in the quarter ended June 30, 2006, with the exception of the quarter ended December 31, 2005 when the gross margin declined to 25.9% primarily as a result of an assembly error affecting certain of our 36 megabit products, which resulted in an inventory write-off of approximately $900,000. The overall improvement in gross margin from June 30, 2005 to December 31, 2006 was primarily a result of a continuing shift in product mix, with a greater proportion of our revenues being generated by our higher margin, higher density products. Reduced product cost due to yield improvement, and various cost reduction measures also contributed to improved gross margins. Gross margin for the quarter ended December 31, 2006 was adversely impacted by a $217,000 book-to-physical adjustment based on the results of a physical inventory taken as of December 31, 2006 and an increase of $92,000 in stock-based compensation due to the issuance of additional stock options.

Research and Development Expenses. Research and development expenses fluctuated from a low of $1.2 million in the quarter ended September 30, 2006 to a high of $1.8 million in the quarter ended September 30, 2005. In the quarter ended September 30, 2005, research and development expenses included $678,000 in pre-production mask set costs related to the transition to new 90 nanometer process technology.

Selling, General and Administrative Expenses. Selling, general and administrative expenses varied from a low of $1.1 million in the quarter ended September 30, 2005 to a high of $1.7 million in the quarter ended December 31, 2006. These expenses fluctuate on a quarterly basis as a result of the timing of expenditures for commission payments to manufacturers' representatives that vary with changes in our net revenues, employee headcount, stock-based compensation expense and travel related and advertising expenses.

Most of our expenses, such as employee compensation and lease payments for facilities, are relatively fixed in the near term. In addition, our expense levels are based in part on our expectations regarding future revenues. As a result, any shortfall in revenues relative to our expectations could cause significant changes in our operating results from quarter to quarter. Our quarterly and annual operating results have fluctuated in the past and are likely to fluctuate significantly in the future due to a variety of factors, including:

•: our ability to attract new customers, retain existing customers and increase sales to such customers;
•: unpredictability of the timing and size of customer orders, since most of our customers purchase our products on a purchase order basis rather than pursuant to a long term contract;
•: changes in our customers' inventory management practices;
•: fluctuations in availability and costs associated with materials needed to satisfy customer requirements;
•: manufacturing defects, which could cause us to incur significant warranty, support and repair costs, lose potential sales, harm our relationships with customers and result in write-downs;
•: changes in our product pricing policies, including those made in response to new product announcements and pricing changes of our competitors; and
•: our ability to address technology issues as they arise, improve our products' functionality and expand our product offerings.

The occurrence of one or more of these factors might cause our operating results to vary widely. As such, we believe that period-to-period comparisons of our revenues and operating results are not necessarily meaningful and should not be relied upon as indications of future performance.

Liquidity and Capital Resources

Since our inception, we have used proceeds from a number of sources, including the private sale of $9.6 million of equity securities, bank borrowings and cash generated by operating activities to support our operations, acquire capital equipment and finance accounts receivable and inventory growth.

As of December 31, 2006, our principal sources of liquidity were $14.9 million in cash, cash equivalents and short term investments, and our $4.0 million line of credit with Mega International Commercial Bank Co., Ltd. Borrowing under our credit line is limited to $1.0 million plus 70.0% of eligible United States accounts receivable balances and 35.0% of finished goods inventory, with a sublimit of $500,000 for inventory. The line of credit expires in May 2007. Although we currently intend to renew the line of credit before it expires, we do not believe its expiration would have a significant impact on our liquidity or capital resources. As of December 31, 2006, no amounts were outstanding under the credit line.

Net cash flow provided by operating activities was $3.4 million for the nine month period ended December 31, 2005 and $138,000 for the nine month period ended December 31, 2006. The primary sources of cash from operating activities in the nine month period ended December 31, 2005 were net income of $2.9 million and a $1.3 million increase in accounts payable due to the timing of wafer purchases from TSMC. These sources were primarily offset by a reduction in accrued expenses and other liabilities resulting from the payment of income taxes. The primary sources of cash from operating activities in the nine month period ended December 31, 2006 were net income of $6.0 million, increases in accounts payable, accrued expenses and other liabilities and deferred revenue. These sources were partially offset by an increase in inventory of $8.1 million as we purchased additional wafers from TSMC to meet anticipated demand and an increase in accounts receivable of

$3.2 million, which reflected the increased quarterly net revenues in the December 2006 quarter compared to the March 2006 quarter.

Net cash flow used in operating activities was $2.2 million in fiscal 2004 compared with net cash provided by operating activities of $8.2 million and $5.2 million in cash in fiscal 2005 and 2006, respectively. Primary uses of cash during fiscal 2004 were our net loss of $670,000, increases in inventory of $8.1 million as we purchased wafers to meet the increasing demand for our products, and a $4.8 million increase in accounts receivable resulting from increased net revenues in the quarter ended March 31, 2004. These uses were partially offset by an increase of $3.6 million in accounts payable, resulting from the increased inventory level, an increase of $2.0 million for accrued expenses and other liabilities, and a decrease of $1.8 million in prepaid expenses and other current assets caused by our receipt of a refund for income taxes previously paid. Principal uses of cash in fiscal 2005 were accounts payable of $2.4 million and deferred income taxes of $1.3 million. Accounts payable in fiscal 2005 decreased compared to fiscal 2004 as we paid for inventory, primarily wafers from TSMC, acquired at the end of fiscal 2004. These fiscal 2005 cash uses were offset primarily by $2.4 million of decreased accounts receivable and $2.7 million of decreased inventory. Inventory levels decreased as we continued to fulfill orders from inventory on hand. The primary use of cash in fiscal 2006 was prepaid expenses and other assets of $1.1 million, accrued expenses and other liabilities of $1.4 million, inventory of $1.7 million and deferred income taxes of $734,000. These uses of cash were partially offset by $3.0 million of increased accounts payable primarily for wafers purchased from TSMC acquired at the end of fiscal 2006.

Net cash used in investing activities was $2.1 million and $2.8 million in the nine month periods ended December 31, 2005 and 2006, respectively. Investment activities consisted primarily of purchases of test equipment in the nine months ended December 31, 2005, expenditures related to the implementation of our new enterprise resource planning, or ERP, system in the nine months ended December 31, 2006 and the investment of excess cash in auction rate securities during each period.

Net cash used in investing activities was $481,000 in fiscal 2004, $3.2 million in fiscal 2005 and $2.2 million in fiscal 2006 and consisted primarily of purchases of test equipment and the investment of excess cash in auction rate securities during each period.

Net cash provided by financing activities was $43,000 and $39,000 in the nine month periods ended December 31, 2005 and 2006, respectively. Net cash provided by financing activities during each period consisted of the net proceeds from the sale of common stock pursuant to option exercises.

Net cash provided by financing activities was $65,000 in fiscal 2004, $50,000 in fiscal 2005 and $46,000 in fiscal 2006. Net cash provided by financing activities during each year consisted of the net proceeds from the sale of common stock pursuant to option exercises.

We had commitments for capital expenditures at December 31, 2006, of approximately $2.5 million. These expenditures will primarily be for test equipment and the implementation of our ERP system. We also have total minimum lease obligations of approximately $1.8 million from January 1, 2007 through May 31, 2010, under non-cancelable operating leases.

We believe that our existing balances of cash and cash equivalents, our available credit facilities and cash flow expected to be generated from our future operations will be sufficient to meet our cash needs for working capital and capital expenditures for at least the next 12 months, although we could be required, or could elect, to seek additional funding prior to that time. Our future capital requirements will depend on many factors, including the rate of revenue growth that we experience, the extent to which we utilize subcontractors, the levels of inventory and accounts receivable that we maintain, the timing and extent of spending to support our product development efforts and the expansion of our sales and marketing efforts. Additional capital may also be required for the consummation of any acquisition of businesses, products or technologies that we may undertake. We

cannot assure you that additional equity or debt financing, if required, will be available on terms that are acceptable or at all.

Contractual Obligations

The following table describes our contractual obligations as of December 31, 2006 under our operating leases for our facilities and test equipment:

		Payments due by period
		Up to 1 year			1-3 years			3-5 years			More than 5 years		Total
Facilities and equipment leases		$	1,101,000		$	581,000		$	118,000		—		$	1,800,000

In addition, we had inventory and mask purchase commitments as well as commitments to purchase test equipment and expenditures for implementation of our ERP system of approximately $9.2 million as of December 31, 2006. These commitments are anticipated to be fulfilled in fiscal 2007.

Critical Accounting Policies and Estimates

The preparation of our financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires us to make judgments and estimates that affect the amounts that we report in our financial statements and accompanying notes. We believe that we consistently apply these judgments and estimates and that our financial statements and accompanying notes fairly represent all periods presented. However, any errors in these judgments and estimates may have a material impact on our balance sheet and statement of operations. Critical accounting estimates, as defined by the Securities and Exchange Commission, are those that are most important to the portrayal of our financial condition and results of operations and require our most difficult and subjective judgments and estimates of matters that are inherently uncertain. Our critical accounting estimates include those regarding revenue recognition, the valuation of inventories, taxes and stock-based compensation.

Revenue Recognition. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectibility is reasonably assured. Under these criteria, revenue from the sale of our products is recognized upon shipment according to our shipping terms, net of accruals for estimated sales returns and allowances based on historical experience. Sales to distributors are made under agreements allowing for returns or credits under certain circumstances. We defer recognition of revenue on sales to distributors until products are resold by the distributor to the end-user.

Our revenue reporting is dependent on receiving pertinent and accurate data from our distributors in a timely fashion. Distributors provide us monthly data regarding the product, price, quantity, and end customer for their shipments as well as the quantities of our products they have in stock at month end. In determining the appropriate amount of revenue to recognize, we use this data in reconciling differences between their reported inventories and activities. If distributors incorrectly report their inventories or activities, it could lead to inaccurate reporting of our revenues and income.

Valuation of Inventories. Inventories are stated at the lower of cost or market, cost being determined on a weighted average basis. Our inventory reserves are established when conditions indicate that the selling price of our products could be less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes. We establish reserves for excess inventory generally based on inventory levels in excess of 12 months of forecasted demand for each specific product. Inventory consists of finished goods, work in progress and goods at distributors. Historically, it has been difficult to forecast customer demand especially at the part-number level. Many of the orders we receive from our customers and distributors request delivery of product on relatively short notice

and with lead times less than our manufacturing cycle time. In order to provide competitive delivery times to our customers, we build and stock a certain amount of inventory in anticipation of customer demand that may not materialize. Moreover, as is common in the semiconductor industry, we may allow customers to cancel orders with minimal advance notice. Thus, even product built to satisfy specific customer orders may not ultimately be required to fulfill customer demand. Nevertheless, at any point in time, some portion of our inventory is subject to the risk of being materially in excess of our projected demand. Additionally, our average selling prices could decline due to market or other conditions, which creates a risk that costs of manufacturing our inventory may not be recovered. For example, in fiscal 2002, as a result of a substantial decline in average selling price, we determined that a significant portion of our inventory was valued in excess of the price at which we could sell the product and recorded an inventory provision of $3.9 million. While we endeavor to accurately predict demand and stock commensurate inventory levels, we may be required to record additional inventory write-downs in the future, which could be material.

Taxes. We make certain estimates and judgments in the calculation of tax liabilities and the determination of deferred tax assets, which arise from temporary differences between tax and financial statement recognition methods. We record a valuation allowance to reduce our deferred tax assets to the amount that management estimates is more likely than not to be realized. If in the future we determine that we are not likely to realize all or part of our net deferred tax assets, an adjustment to deferred tax assets would be charged to earnings in the period such determination is made.

In addition, the calculation of tax liabilities involves inherent uncertainty in the application of complex tax laws. We record tax reserves for additional taxes that we estimate we may be required to pay as a result of future potential examinations by federal and state taxing authorities. If the payment ultimately proves to be unnecessary, the reversal of these tax reserves would result in tax benefits being recognized in the period we determine such reserves are no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, an additional charge to expense will result.

Stock Based Compensation. Information regarding our stock option grants to our employees during fiscal 2006 and for the nine months ended December 31, 2006 is summarized as follows:

Date of Issuance	Number of Shares Subject to Options Granted	Exercise Price Per Share		Estimated Fair Value of Common Stock		Intrinsic Value Per Share
June 2005 through October 2005	130,400	$	4.50	$	4.50	$	—
August 2006	16,800	$	5.50	$	5.50	$	—
August 2006 through September 2006	159,200	$	5.75	$	5.75	$	—
October 2006 through November 2006	994,169	$	5.50	$	5.50	$	—

Prior to April 1, 2006, we accounted for employee stock options using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees ("APB 25"), and Financial Accounting Standards Board ("FASB") Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB No. 25, and had adopted the disclosure-only provisions using the fair value method of SFAS No. 123, Accounting for Stock-Based Compensation ("SFAS 123"), and SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. In accordance with APB 25, we recognized compensation cost for options granted to the extent the exercise price was lower than the fair value of the underlying common stock on the date of grant. Prior to April 1, 2006, we allocated stock-based compensation costs using the straight line method and recognized the effect of forfeitures when they occurred.

On April 1, 2006, we adopted SFAS No. 123(R), Share-Based Payment ("SFAS 123(R)"), using the modified prospective transition method. Under this method, our stock-based compensation costs recognized during the nine months ended December 31, 2006 were comprised of compensation costs for all share-based payment awards granted subsequent to April 1, 2006 and of compensation costs

related to share-based payment awards that were unvested on April 1, 2006, based on their grant-date fair value estimated using the Black-Scholes option pricing model. Prior periods were not restated. As stock-based compensation expense recognized in the statement of operations for the nine months ended December 31, 2006 is based on options ultimately expected to vest, it has been reduced by the amount of estimated forfeitures.

We chose the straight-line method of allocating compensation cost over the requisite service period of the related award under SFAS 123(R). We calculated the expected term based on the historical average period of time that options were outstanding as adjusted for expected changes in future exercise patterns, which, for options granted in the nine months ended December 31, 2006, resulted in an expected term of approximately four years. We based our estimate of expected volatility on the estimated volatility of similar entities whose share prices are publicly available. The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding to the expected life of the options. The dividend yield is 0%, based on the fact that we have never paid dividends and have no present intention to pay dividends. Changes to these assumptions may have a significant impact on the results of operations.

The impact of adoption of SFAS 123(R) was to reduce income before tax by $809,000, net income by $787,000 and basic and diluted net income per share by $0.13 and $0.03, respectively, for the nine months ended December 31, 2006. SFAS 123(R) requires cash flows, if any, resulting from the tax benefits from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows. Adoption of FAS No. 123(R) did not have an impact on operating and financing cash flows because we did not have any excess tax benefits in the period of adoption.

Prior to the adoption of SFAS No. 123(R), we recognized forfeitures of unvested stock options as they occurred. Upon adoption of SFAS No. 123(R), we began estimating future forfeitures and recognizing the effect of such forfeitures on the grant date of the awards. SFAS No. 123(R) requires a one-time cumulative adjustment at the adoption date to record an estimate of future forfeitures on the unvested outstanding awards. Based on our estimate of the impact of future forfeitures on the expense recognized for unvested options at the date of adoption, such one-time cumulative adjustment was determined to be immaterial.

We have no stock-based compensation arrangements with non-employees.

Given the absence of an active market for our common stock, our board of directors estimated the fair value of our common stock for purposes of determining stock-based compensation expense for the periods presented. Through September 2006, the board of directors determined the estimated fair value of our common stock, based in part on our historic net revenues and a market determined revenue multiplier as well as the following:

•: the prices for our convertible preferred stock sold to investors in arms-length transactions, and the rights, preferences and privileges of that redeemable convertible preferred stock relative to those of our common stock;
•: the launch of new products;
•: our financial position, historic operating results and revenue growth;
•: the fact that the option grants involved illiquid securities in a private company; and
•: the likelihood of achieving a liquidity event, such as an initial public offering or sale of the company, for the shares of common stock underlying the options given prevailing market conditions.

In October 2006, we obtained an independent valuation from Duff & Phelps, LLC of our common stock as of September 30, 2006 which assisted in our determination of value for grants made from October 2006 to November 21, 2006.

We believe that we have used reasonable methodologies, approaches and assumptions consistent with the American Institute of Certified Public Accountants Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation, to determine the fair value of our common stock. If we had made different assumptions and estimates than those described above, the amount of our recognized and to be recognized stock-based compensation expense, net income (loss) and net income (loss) per share amounts could have been materially different.

Based upon the initial public offering price of $5.50 per share, the aggregate intrinsic values of vested and unvested options to purchase shares of our common stock outstanding as of December 31, 2006 were $7.8 million and $785,000, respectively.

Off-Balance Sheet Arrangements

At December 31, 2006, we did not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Accordingly, we are not exposed to the type of financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Quantitative and Qualitative Disclosure Regarding Market Risk

Foreign Currency Exchange Risk. Our revenues and expenses, except those expenses related to our operations in Taiwan, including subcontractor manufacturing expenses, are denominated in U.S. dollars. As a result, we have relatively little exposure for currency exchange risks, and foreign exchange losses have been minimal to date. We do not currently enter into forward exchange contracts to hedge exposure denominated in foreign currencies or any other derivative financial instruments for trading or speculative purposes. In the future, if we feel our foreign currency exposure has increased, we may consider entering into hedging transactions to help mitigate that risk.

Interest Rate Sensitivity. We had unrestricted cash, cash equivalents and short term investments totaling $14.9 million at December 31, 2006. These amounts were invested primarily in money market funds and auction rate securities. The unrestricted cash, cash equivalents and short-term marketable securities are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of these investments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, will reduce future investment income.

Recent Accounting Pronouncements

In February 2007, the Financial Accounting Standards Board, or FASB, issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities," which permits entities to choose to measure eligible financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the effect that the adoption of SFAS 159 will have on our consolidated financial position and results of operations.

In September 2006, the Securities and Exchange Commission, or SEC, issued Staff Accounting Bulletin No. 108, or SAB No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements, which provides interpretive guidance on how the

effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. We will be required to adopt the provisions of SAB No. 108 in fiscal 2008. We do not believe the adoption of SAB No. 108 will have a material impact on our consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. SFAS No. 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements. The changes to current practice resulting from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. We will be required to adopt the provisions of SFAS No. 157 beginning with our fiscal quarter ending June 30, 2008. We do not believe the adoption of SFAS No. 157 will have a material impact on our consolidated financial position, results of operations or cash flows

In July 2006, the FASB, issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement 109, or FIN 48. FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). Under the Interpretation, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts, but without considering time values. The Interpretation substantially changes the applicable accounting model and is likely to cause greater volatility in income statements as more items are recognized discretely within income tax expense. The Interpretation also revises disclosure requirements and introduces a prescriptive, annual, tabular roll-forward of the unrecognized tax benefits. The Interpretation requires qualitative and quantitative disclosures, including discussion of reasonably possible changes that might occur in the recognized tax benefits over the next 12 months; a description of open tax years by major jurisdictions; and a roll-forward of all unrecognized tax benefits, presented as a reconciliation of the beginning and ending balances of the unrecognized tax benefits on a worldwide aggregated basis. The Interpretation is effective as of the beginning of fiscal years that start after December 15, 2006. We are currently evaluating the effect that the adoption of FIN 48 will have on our consolidated results of operations and financial condition.

In June 2006, EITF No. 06-3, How Sales Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross Versus Net Presentation) was issued, which states that a company must disclose its accounting policy (i.e., gross or net presentations) regarding presentations of taxes within the scope of EITF No. 06-03. If taxes included in gross revenue are significant, a company must disclose the amount of these taxes for each period for which an income statement is presented. The disclosures are required for annual and interim financial statements for each period for which an income statement is presented. EITF No. 06-03 will be effective for us beginning April 1, 2007. Based on our current evaluation of EITF No. 06-03, we do not expect its adoption to have a material impact on our consolidated results of operations or financial position.

BUSINESS

Overview

We are a provider of "Very Fast" static random access memory, or SRAM, products that are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, we serve the ongoing needs of the military, industrial, test equipment and medical markets for high-performance SRAMs. Based on the performance characteristics of our products and the breadth of our product portfolio, we consider ourselves to be a leading provider of Very Fast SRAMs.

We work closely with system designers at leading original equipment manufacturer, or OEM, customers including Alcatel-Lucent, Cisco Systems, Huawei Technologies and Nortel Networks, to better anticipate their needs and gain insight into future technology requirements. We believe that our success with customers is due to our offering the broadest available catalog of high-performance SRAMs to meet their highly specialized needs, combined with superior customer service over the lifetime of our products. We utilize a fabless business model, which allows us both to focus our resources on research and development, product design and marketing, and to gain access to advanced process technologies with only modest capital investment and fixed costs.

Industry Background

SRAM Market Overview

Virtually all types of high-performance electronic systems incorporate SRAMs. An SRAM is a memory device that retains data as long as power is supplied, without requiring any further user intervention. SRAMs offer the fastest access to stored data of any type of memory device.

There are a broad variety of SRAMs, characterized by a number of attributes, such as speed, memory capacity, or density, and power consumption. There are several different industry measures of speed:

•: latency, also referred to as random access time, which is the delay between the request for data and the delivery of such data for use and is measured in nanoseconds, or ns;
•: bandwidth, which is the rate at which data can be streamed to or from a device and is measured in gigabits per second;
•: clock frequency, which is the cycle rate of a clock within a synchronous device and is measured in megahertz, or MHz; and
•: clock access time, which is the delay between the beginning of the clock cycle and the delivery of data as measured in nanoseconds.

Historically, SRAMs have been utilized wherever other memory technologies have been inadequate. SRAMs demonstrate lower latency, resulting in faster random access times, relative to dynamic random access memory, or DRAM, and other types of memory technologies. However, over the past few decades, less expensive alternatives have been introduced to address certain applications formerly using lower performance SRAMs. For example, new types of DRAM are now in the process of displacing lower performance SRAM products in applications such as cell phones. As a result of the displacement of low performance SRAMs, the total market size for SRAMs is diminishing. However, due to their inherent higher latency characteristics, DRAMs cannot match the random access speed of high-performance SRAMs. Gartner Dataquest divides the SRAM market into segments based on speed. The highest performance segment is comprised of SRAMs that operate at speeds of less than 10 nanoseconds, which we refer to as "Very Fast SRAMs." Very Fast SRAMs are predominantly

utilized in high-performance networking and telecommunications equipment. Gartner Dataquest estimates that this segment of the SRAM market will grow from $1.06 billion in 2006 to $1.12 billion in 2010.

Increasing Need for Very Fast SRAMs

Growth in data, voice and video traffic has driven the need for greater networking bandwidth, resulting in the continued expansion of the networking and telecommunications infrastructure. The continued growth in the level of Internet usage has led to the proliferation of a wide variety of equipment throughout the networking and telecommunications infrastructure, including routers, switches, wireless local area network infrastructure equipment, wireless base stations and network access equipment and a demand for new equipment with faster and higher performance. High-performance networking and telecommunications equipment requires Very Fast SRAMs. For example, in a typical router or switch, multiple Very Fast SRAMs are required to temporarily store, or buffer, data traffic and to provide rapid lookup of information in data tables. As networking equipment must increasingly support advanced traffic content such as Voice over Internet Protocol, or VoIP, and video streaming, demand for even higher performance Very Fast SRAMs is expected to continue to increase.

Demanding Requirements for Success in the Very Fast SRAM Market

The pressure on networking and telecommunications OEMs to bring higher performance equipment to market rapidly to support not only more traffic but also more advanced traffic content is compounded by the requirement that this new equipment occupy no more space than the equipment it replaces, which results in increased board density and the need for low power operations. In response to these pressures, OEMs have increasingly relied on providers that are capable of rapidly developing and introducing advanced, higher density, low power Very Fast SRAMs. The variety of applications for Very Fast SRAMs within the networking and telecommunications markets has also driven a need for more specialized products available in relatively low volumes. These specialized products include high-speed synchronous SRAMs, with different density, latency and bandwidth capabilities. In general, OEMs prefer to work with a supplier who can address the full range of their high-performance Very Fast SRAM product requirements and, just as importantly, can offer the technical and logistic support necessary to sustain and accelerate their efforts.

We believe the key success factors for a Very Fast SRAM vendor are the ability to offer a broad catalog of high-performance, high-quality and high-reliability Very Fast SRAM products, to continuously introduce new products with higher speeds, lower power and greater densities, to maintain timely availability of prior generations of products for several years after their introductions, and to provide effective logistic and technical support throughout OEM customers' product development and manufacturing life cycles.

The GSI Solution

We endeavor to address the overall needs of our OEM customers for Very Fast SRAMs, not only satisfying their immediate requirements for our latest generation, highest performance ICs but also providing them with the ongoing long-term support necessary during the entire lives of the systems in which our products are utilized. Accordingly, the key elements of our solution include:

Innovative Product Performance Leadership

High Speed. Through the use of advanced architectures, design methodologies and silicon process technologies, we have developed a wide variety of high-performance Very Fast SRAMs. The vast majority of our products have random access times of 9 nanoseconds or less, while our newest products have random access times of less than 5 nanoseconds and clock access times as fast as

0.45 nanoseconds with bandwidth as high as 48 gigabits per second. By providing higher performance Very Fast SRAMs, we enable our networking and telecommunications OEMs to continually design and develop higher performance products that support increasingly complex traffic content.

Low Power Consumption. Many of our Very Fast SRAMs require significantly less power than comparable products offered by our principal competitors. Because these products utilize less power and generate less heat, the reliability of the networking or telecommunications equipment in which they are employed increases. Furthermore, the low power utilization of our Very Fast SRAMs helps enable OEMs to add capabilities to their systems, which otherwise might not have been possible due to overall system power constraints.

Process Technology Leadership. We maintain our own process engineering capability and resources, which are located in close physical proximity to our manufacturer, TSMC. This enhances our ability to work closely with TSMC to develop certain modifications of the advanced process technologies used in the manufacturing of our Very Fast SRAMs in order to maximize product performance, optimize yields, lower manufacturing costs and improve quality. Our most advanced 36 and 72 megabit, or Mb, synchronous Very Fast SRAMs are manufactured using 90 nanometer process technology. We are currently developing new synchronous Very Fast SRAMs using 65 nanometer process technology, which will allow us to further increase product performance, lower power consumption and reduce costs.

Product Innovation. We believe we have established a position as a technology leader in the design and development of Very Fast SRAMs. For example, we were the first supplier to introduce 72-bit-wide SRAMs as single monolithic ICs. In addition, we are the only vendor to offer a full line of Very Fast Synchronous SRAMs that operate and interface at 1.8 to 3.3 volts, giving our OEM customers the ability to use the same product in systems of theirs that operate at any voltage within that range. Moreover, for certain Very Fast Synchronous SRAMs, we are the only vendor to offer a product that operates at 1.8 volts, which uses approximately one half to two-thirds the power of our competitors' 2.5 volt products.

Broad and Readily Available Product Portfolio

Extensive Product Catalog. The Very Fast SRAM market is highly fragmented in terms of product features and specifications. To meet our OEM customers' diverse needs, we have what we believe is the broadest catalog of Very Fast SRAM products currently available. Our product line includes a wide range of Very Fast SRAMs with varying densities, features, clock speeds, and voltages, as well as several operating temperature ranges and numerous package options in both 5/6 (leaded) and 6/6 (lead-free) versions, which are compliant with the European Union's Restriction on the Use of Hazardous Substances Directive 2002/95/EC.

Advanced Feature Sets. Our products offer features that address a broad range of our networking and telecommunications OEMs' system requirements. Among these features is a JTAG test port, named for the IEEE Joint Test Action Group, which enables post-assembly verification of the connection between our Very Fast SRAMs and an OEM customer's system board, thereby allowing an OEM customer of ours to develop, test and ship their products more rapidly. Additionally, we offer our FLXDrive feature, which allows system designers to optimize the signal integrity for any given requirement. We also provide OEMs the ability to employ certain of our Very Fast SRAMs in various modes of operation by using our products' mode control pins, thus increasing the flexibility of those products and their ready availability from our inventory.

Superior Lifetime Availability of Products. Unlike the market for consumer electronics, the markets in which we compete, particularly the networking and telecommunications market, generally keep their system designs in production for extended periods of time and maintenance of those systems in the field for even longer periods is critical to their success. Our foundry-based manufacturing strategy, our

process technology selections, our master-die design strategy and the design of our packaging, burn-in and test work-flows all contribute to allow us to meet and exceed our guarantee of providing a product life of at least seven years for any new product family we bring to market. These techniques also allow us to keep our delivery lead-times relatively short even for specialized, infrequently ordered members of those product families. We believe our approach is better suited to address the needs of our target markets than attempts to apply mass market manufacturing strategies to Very Fast SRAM products.

Multiple Temperature Grades. We offer both commercial and industrial temperature grades for all of our Very Fast SRAMs. This ability to perform at specification throughout the industrial temperature range of -40°C to +85°C is critical for Very Fast SRAMs used in a broad variety of networking and telecommunications applications, where the operating environments may be harsh. We can also offer military and extended temperature grades upon request for most of our Very Fast SRAMs.

Master Die Methodology

Our master die methodology enables multiple product families, and variations thereof, to be manufactured from a single mask set. As a result, based upon the way available die from a wafer are metalized, wire bonded, packaged and tested, from 19 mask sets we have created over 8,500 different products. Using these mask sets, we produce wafers that can be further processed upon customer orders into the final specified product thereby significantly shortening the overall manufacturing time. For example, from a 72 megabit mask set, we can produce three families of 72 megabit SRAM products. Our unique methodology results in the following benefits:

Rapid Order Fulfillment. We maintain a common pool of wafers that incorporate all available master die. Because we can typically create several different products from a single master die, we can respond to unforecasted customer orders more quickly than our competitors.

Reduced Cost. Our master die methodology allows us to reduce our costs through the purchase of fewer mask sets by allowing faster and less expensive internal product qualifications, by enabling more cost-efficient use of engineering resources and by reducing the incidence of obsolete inventory.

Customer Responsiveness

Customer-driven Solutions. We work closely with leading networking and telecommunications OEMs, as well as their chip-set suppliers, to better anticipate their requirements and to rapidly develop and implement solutions that allow them to meet their specific product performance objectives. Customer demand drives our business. For example, to address near term needs, we offer critical specification variations, such as special operating ranges or wire bond options on currently available products, while we also design new families of products to meet their emerging long term needs. As a consequence, our portfolio not only includes the widest select of catalog parts available, it also includes an extensive list of custom, customer-specific products. This degree of responsiveness enables us to provide our OEM customers with the Very Fast SRAMs required for their applications.

Accelerated Time-to-market. Our extensive open libraries of design support tools as well as our ability to deliver the specific device required for system prototyping with very short notice enables networking and telecommunication OEMs to design and introduce differentiated products quickly as well as to reduce their development costs. Our open libraries give designers access 24 hours a day, seven days a week to electrical and behavioral simulation models. Behavioral models are offered in both Verilog and VHDL format to better fit different customers' simulation environments, further streamlining the customers' development process.

Quality and Reliability. Networking and telecommunications equipment typically have long product lives, and the cost to repair or replace this equipment due to product failure at any time is prohibitively expensive. The high-quality and reliability of Very Fast SRAMs incorporated in our OEM customers'

products is, thus, critical. Every product family we offer is subjected to extensive long term reliability testing before receiving qualification certification, and every Very Fast SRAM shipped is first subjected to burn-in and then to final tests in which the SRAM is operated beyond its specified operating voltage and temperature ranges.

The GSI Strategy

Our objective is to profitably increase our market share in the Very Fast SRAM market. Our strategy includes the following key elements:

Continue to Focus on the Networking and Telecommunications Markets. We intend to continue to focus on designing and developing low latency, high bandwidth and feature-rich memory products targeted primarily at the networking and telecommunications markets. Increasing network complexity due to higher traffic volume and more advanced traffic content continues to drive OEMs' demand for high-performance Very Fast SRAMs. We believe our active high-performance SRAM development and manufacturing expertise will continue to allow us to provide networking and telecommunications OEMs with the early access to next generation Very Fast SRAMs that offer superior performance, advanced feature sets and continued high reliability, which they need to allow them to design and develop new products that support increasingly complex traffic content and to bring networking and telecommunications equipment to market quickly.

Strengthen and Expand Customer Relationships. We are focused on maintaining close relationships with industry leaders to facilitate rapid adoption of our products and to enhance our position as a leading provider of high-performance Very Fast SRAM. We work with both our customers and with their non-memory integrated circuit, or IC, suppliers that require high-performance memory support. We will continue to work with both groups at the pre-design and design stage of their projects in order to anticipate their future high-performance memory needs and to identify and respond to their immediate requests for currently available products and variants on currently available products. We plan to enhance our relationships with those leading OEMs and IC vendors and to develop similar relationships with additional OEMs and IC vendors.

Continue to Invest in Research and Development to Extend Our Technology Leadership. We believe we have established a position as a technology leader in the design and development of Very Fast SRAMs. Our Very Fast SRAM products most often provide the highest speed available at a given density for a given device configuration. We intend to maintain and advance our technology leadership through continual enhancement of our existing Very Fast SRAM products, particularly our SigmaQuad family of low latency, high-bandwidth synchronous SRAMs while we continue to broaden our product line with the introduction of other new Very Fast SRAMs.

Collaborate with Wafer Foundries to Leverage Leading-edge Process Technologies. We will continue to rely upon advanced complementary metal oxide semiconductor, or CMOS, technologies, the most commonly used process technologies for manufacturing semiconductor devices, from TSMC, to manufacture our products and will continue to provide TSMC with the sort of in-depth feedback for yield and performance improvement that can best come from very large array structures like those found on our products. Our most advanced products currently in production were designed using 90 nanometer process technology on 300 millimeter wafers. We intend to continue to collaborate closely with TSMC in the refinement of 65 nanometer process technology.

Exploit New Market Opportunities. While we design our Very Fast SRAMs specifically for the networking and communications sections, our products are applicable across a wide range of industries and applications. We have recently experienced significant growth in both the defense and medical markets and intend to continue penetrating these and other new markets with similar needs for high-performance memory technologies.

Products

We design, develop and market a broad range of high-performance Very Fast SRAMs primarily for the networking and telecommunications markets. We specialize in Very Fast SRAMs featuring high density, low latency, high bandwidth, fast clock access times and low power consumption. We currently offer more than 30 basic product configurations of our SRAMs based on their basic product type and their storage densities. We continue to offer products for longer periods of time than our competitors, typically seven years or more following their initial introduction. Accordingly, we continue to offer products in a variety of package types that have been discontinued by other suppliers. Our current product configurations are as follows:

The foregoing product configurations are the basis for over 8,500 individual products that incorporate a variety of performance specifications and optional features. Our products can be found in a wide range of networking and telecommunications equipment, including multi-service access routers, universal gateways, enterprise edge routers, service provider edge routers, optical edge routers, fast Ethernet switches, gigabit Ethernet switches, wireless base stations, ADSL modems, wireless local area networks, Internet Protocol phones and OC192 layer 2 switches. We also sell our products to OEMs that manufacture products for defense applications such as radar and guidance systems, for professional audio applications such as sound mixing systems, for test and measurement applications such as high-speed testers, for automotive applications such as smart cruise control and voice recognition systems, and for medical applications such as ultrasound and CAT scan equipment.

Synchronous SRAM Products

Synchronous SRAMs are controlled by timing signals, referred to as clocks, which make them easier to use than older style asynchronous SRAMs with similar latency characteristics in applications requiring high bandwidth data transfers. Synchronous SRAMs that employ double data rate interface protocols can transfer data at much higher bandwidth than both single data rate and asynchronous SRAMs. Our single data rate synchronous SRAMs feature clock access times as short as 2 nanoseconds and our double data rate synchronous SRAMs have clock access times as fast as 0.45 nanoseconds. Today, we supply synchronous SRAMs that can cycle at operating frequencies as high as 357 MHz.

Burst and NBT SRAMs. We currently offer BurstRAMs and No Bus Turnaround, or NBT, SRAMs that implement a single data rate bus protocol. BurstRAMs were originally developed for microprocessor cache applications and have become the most widely used synchronous SRAM on the market. They are used in applications where large amounts of data are read or written in single sessions, or bursts. NBT SRAMs are a variation on the BurstRAM theme that were developed to address the needs of moderate performance networking applications. NBT SRAMs feature a single data rate bus protocol designed to minimize or eliminate wasted data transfer time slots on the bus when BurstRAMs switch from read to write operations. Both families of products can perform burst data transfers or single cycle transfers at the discretion of the user.

Our BurstRAMs and NBT SRAMs are offered in both pipeline and flow-through modes. Flow-through SRAMs allow the shortest latency. Pipelined SRAMs break the access into discrete clock-controlled steps, allowing new access commands to be accepted while an access is already in progress. Therefore, while flow-through SRAMs offer lower latency, pipelined SRAMs offer greater data bandwidth. Our BurstRAM and NBT SRAM products incorporate a number of features that reduce our OEM customers' cost of ownership and increase their design flexibility, including a JTAG test port and our FLXDrive feature, which allows system designers to optimize signal integrity for a given application.

We currently offer BurstRAMs and NBT SRAMs with storage densities of up to 72 megabits with clock frequency of up to 333 MHz and clock access times as fast as 2 nanoseconds that operate at 3.3, 2.5 or 1.8 volts.

SigmaQuad Products. High-performance quad data rate synchronous SRAMs have become the de facto standard for the networking and telecommunications industry. We offer a full line of quad data rate SRAMs, our SigmaQuad family. Quad data rate SRAMs are separate input/output, or I/O, synchronous SRAMs that features two independent double data rate data ports (two data ports times double data rate transfers equals quad data rate) controlled via a single address and control port. We offer our SigmaQuad devices in two different bus protocol versions, two different power supply and interface voltage versions, with two different data burst length options, all under the name SigmaQuad or SigmaQuad-II. In addition, the family also includes derivative products including a family of common I/O (a single bi-directional data port) double data rate SRAMs known as SigmaCIO DDR-II SRAMs and a smaller family of double data rate separate I/O SRAMs designed to address some segments of the market currently served by dual-port SRAMs, known as SigmaSIO DDR-II SRAMs.

We currently offer SigmaQuad products in three storage densities, 18 megabits, 36 megabits and 72 megabits, with clock frequency rates up to 333 MHz and clock access times as fast as 0.45 nanoseconds, that operate at voltages of 2.5 and 1.8 volts.

SigmaRAM Products. We offer a family of high-performance, low voltage, HSTL, or high speed transceiver logic, I/O synchronous SRAM products based on the SigmaRAM architecture, which are designed for use on large format printed circuit boards common in many networking and telecommunication products. These SRAMs utilize a unique architecture that provides the capability to incorporate the full range of popular SRAM functionality, including late write and double late write

protocols, pipelined read cycles, burst data transfers, and double data rate read and write data transfers in common I/O format.

We currently offer SigmaRAM products with storage density of 18 megabits, speeds of up to 350 MHz and clock access times as fast as 1.7 nanoseconds that operate at 1.8 volts.

Asynchronous SRAM Products

Unlike synchronous SRAMs, asynchronous SRAMs employ a clock-free control interface. They are widely used in support of high-end digital signal processors, or DSPs. We believe we have one of the broadest portfolios of 3.3 volt, high-speed asynchronous SRAMs. These products are designed to meet the stringent power and performance requirements of networking and telecommunications applications, such as VoIP, cellular base stations, DSL line cards and modems.

We currently offer asynchronous SRAM products with a variety of storage densities between 1 megabits and 8 megabits and random access times ranging from 7 nanoseconds to 15 nanoseconds. All of our asynchronous SRAMs operate at 3.3 volts.

We intend to regularly introduce new products with high-performance advanced features of increasing complexity. These product solutions will require us to achieve volume production in a rapid timeframe. We believe that by using the advanced technologies offered by our fabrication partner and its expertise in high-volume manufacturing, we can rapidly achieve volume production. However, lead times for materials and components we order vary significantly and depend on such factors as the specific supplier, contract terms and demand for a component at a given time.

Customers

Our primary sales and marketing strategy is to achieve design wins with OEM customers who are leading networking and telecommunications companies. The following is a representative list of our OEM customers that have directly or indirectly purchased more than $400,000 of our products in the fiscal year ended March 31, 2006:

3Com	Agilent Technologies	Huawei Technologies
ADC Telecommunications	Alcatel-Lucent	Nortel Networks
Agere Systems	Cisco Systems	Tekelec

Many of our OEM customers use contract manufacturers to assemble their equipment. Accordingly, a significant percentage of our net revenues is derived from sales to these contract manufacturers and to consignment warehouses who purchase products from us for use by contract manufacturers. In addition, we sell our products to networking and telecommunications OEM customers indirectly through domestic and international distributors.

In the case of sales of our products to distributors and consignment warehouses, the decision to purchase our products is typically made by the OEM customers. In the case of contract manufacturers, OEM customers typically provide a list of approved products to the contract manufacturer, which then has discretion whether or not to purchase our products from that list.

Direct sales to contract manufacturers and consignment warehouses accounted for 38.8%, 38.8%, 35.0% and 36.4% of our net revenues for fiscal 2004, 2005 and 2006, and for the nine months ended December 31, 2006, respectively. Sales to foreign and domestic distributors accounted for 46.8%, 49.7%, 55.7% and 56.5% of our net revenues for fiscal 2004, 2005 and 2006, and for the nine months ended December 31, 2006, respectively.

The following direct customers accounted for 10% or more of our net revenues in one or more of the following periods:

		Fiscal Year Ended March 31,						Nine Months Ended December 31,
		2004		2005		2006		2005		2006
Consignment warehouses:
	SMART Modular Technologies	27.1	%	31.8	%	27.3	%	27.4	%	31.3	%
Distributors:
	Avnet Logistics	32.0		32.5		30.4		32.7		24.2
	Nu Horizons	3.0		6.1		10.3		9.4		8.4

Cisco Systems, our largest OEM customer, purchases our products primarily through its consignment warehouse, SMART Modular Technologies, and also purchases some products through its contract manufacturers and directly from us. Based on information provided to us by Cisco Systems' consignment warehouse, and contract manufacturers, purchases by Cisco Systems represented approximately 31%, 34%, 28% and 32% of our net revenues in fiscal 2004, 2005 and 2006 and the nine months ended December 31, 2006, respectively.

Sales, Marketing and Technical Support

We sell our products primarily through our worldwide network of independent sales representatives and distributors. As of December 31, 2006, we employed 16 sales and marketing personnel, and are supported by over 200 independent sales representatives. We have recently entered into an arrangement with Arrow Electronics, a leading distributor, to distribute our products in the U.S. market. We believe that this new relationship, along with our two other U.S. distributors, Avnet and Nu Horizons, puts us in a strong position to address the Very Fast SRAM market in the U.S. In addition, to expand our international business, we have recently entered into new arrangements with sales representatives and distributors in Japan and Europe that we believe will enable us to increase our market share in these important markets. We currently have regional sales offices located in Canada, China, Italy and the United States. We believe this international coverage allows us to better serve our distributors and OEM customers by providing them with coordinated support. We believe that our customers' purchasing decisions are based primarily on product performance, availability, features, quality, reliability, price, manufacturing flexibility and service. Many of our OEM customers have had long-term relationships with us based on our success in meeting these criteria.

Our sales are generally made pursuant to purchase orders received between one and six months prior to the scheduled delivery date. Because industry practice allows customers to reschedule or cancel orders on relatively short notice, these orders are not firm and hence we believe that backlog is not a good indicator of our future sales. We typically provide a warranty of up to 36 months on our products. Liability for a stated warranty period is usually limited to replacement of defective products.

Our marketing efforts are focused on increasing brand name awareness and providing solutions that address our customers' needs. Key components of our marketing efforts include maintaining an active role in industry standards committees, such as the JEDEC Solid State Technology Association (formerly the Joint Electron Device Engineering Council), or JEDEC, which is responsible for establishing detailed specifications, which can be utilized in future system designs. We believe that our participation in and sponsorship of numerous proposals within these committees have increased our profile among leading manufacturers in the networking and telecommunications segment of the Very Fast SRAM market. Our marketing group also provides technical, strategic and tactical sales support to our direct sales personnel, sales representatives and distributors. This support includes in-depth product presentations, datasheets, application notes, simulation models, sales tools, marketing communications, marketing research, trademark administration and other support functions.

We emphasize customer service and technical support in an effort to provide our OEM customers with the knowledge and resources necessary to successfully use our products in their designs. Our customer service organization includes a technical team of applications engineers, technical marketing personnel and, when required, product design engineers. We provide customer support throughout the qualification and sales process and continue providing follow-up service after the sale of our products and on an ongoing basis. In addition, we provide our OEM customers with comprehensive datasheets, application notes and reference designs.

Manufacturing

We outsource our wafer fabrication, assembly and a majority of our testing, which enables us to focus on our design strengths, minimize fixed costs and capital expenditures and gain access to advanced manufacturing technologies. Our engineers work closely with our outsource partners to increase yields, reduce manufacturing costs, and help assure the quality of our products.

Currently, all of our wafers are manufactured by TSMC under individually negotiated purchase orders. We do not currently have a long-term supply contract with TSMC, and therefore, TSMC is not obligated to manufacture products for us for any specified period, in any specified quantity or at any specified price, except as may be provided in a particular purchase order. Our future success depends in part on our ability to secure sufficient capacity at TSMC or other independent foundries to supply us with the wafers we require.

Most of our products are implemented using 0.13 micron and 90 nanometer process technologies on 300 millimeter wafers using process technology developed by TSMC. We currently have five separate product families in production using the 0.13 micron process. Our 72 megabit SigmaQuad and 72 megabit synchronous BurstRAM and NBT SRAM products are currently manufactured using 90 nanometer process technology. We expect to introduce our 36 megabit SigmaQuad using 90 nanometer process technology in the first calendar quarter of 2007. We are also developing new synchronous SRAMs using 65 nanometer process technology.

Our master die methodology enables multiple product families, and variations thereof, to be manufactured from a single mask set. As a result, based upon the way available die from a wafer are metalized, wire bonded, packaged and tested, we can create a number of different products. The manufacturing process consists of two phases, the first of which takes approximately eight to twelve weeks and results in wafers that have the potential to yield multiple products within a given product family. After the completion of this phase, the wafers are stored pending customer orders. Once we receive orders for a particular product, we perform the second phase, consisting of final wafer processing, assembly, burn-in and test, which takes approximately six to ten weeks to complete. This two-step manufacturing process enables us to significantly shorten our product lead times, providing flexibility for customization and to increase the availability of our products.

All of our manufactured wafers are tested for electrical compliance and most are packaged at Advanced Semiconductor Engineering, or ASE, which is located in Taiwan. Our test procedures require that all of our products be subjected to accelerated burn-in and extensive functional electrical testing, most of which occur at Sigurd Microelectronics Co. and King Yuan Electronics Company. We perform testing for most of our low volume products in-house at our Santa Clara, California and our Taiwan facilities.

Research and Development

The design process for our products is complex. As a result, we have made substantial investments in computer-aided design and engineering resources to manage our design process. Research and development expenses were $3.8 million in the nine months ended December 31, 2006, $5.4 million in fiscal 2006, $4.8 million in fiscal 2005 and $5.5 million in fiscal 2004. Our research and development

staff includes engineering professionals with extensive experience in the areas of SRAM design and systems level networking and telecommunications equipment design. Our current development focus is on the SigmaQuad SRAM family.

We are also leveraging our advanced design capabilities to expand into other networking and telecommunications products, including a channelized OC-3 processor that incorporates 20 megabits of SRAM. When completed, we believe this will be the first low-power, single IC device solution capable of simultaneously processing multiple types of traffic with OC-3 bandwidth. We have established a design center in Norcross, Georgia, to focus on the development of these products.

Competition

Our existing competitors include many large domestic and international companies, some of which have substantially greater resources, offer other sorts of memory and/or non-memory technologies and may have longer standing relationships with OEM customers than we do. Unlike us, some of our principal competitors maintain their own semiconductor fabs, which may, at times, provide them with capacity, cost and technical advantages.

Our principal competitors include Cypress Semiconductor, Integrated Device Technology, Integrated Silicon Solution, NEC, Renesas and Samsung Electronics. While some of our competitors offer a broad array of memory products and offer some of their products at lower prices than we do, we believe that our focus on and performance leadership in low latency, high density Very Fast SRAMs provide us with key competitive advantages.

We believe that our ability to compete successfully in the rapidly evolving markets for Very Fast SRAM products depends on a number of factors, including:

•: product performance, features, quality, reliability and price;
•: manufacturing flexibility, product availability and customer service throughout the lifetime of the product;
•: the timing and success of new product introductions by us, our customers and our competitors; and
•: our ability to anticipate and conform to new industry standards.

We believe we compete favorably with our competitors based on these factors. However, we may not be able to compete successfully in the future with respect to any of these factors. Our failure to compete successfully in these or other areas could harm our business.

The market for Very Fast SRAM products is competitive and is characterized by technological change, declining average selling prices and product obsolescence. Competition could increase in the future from existing competitors and from other companies that may enter our existing or future markets with solutions that may be less costly or provide higher performance or more desirable features than our products. This increased competition may result in price reductions, reduced profit margins and loss of market share.

In addition, we are vulnerable to advances in technology by competitors, including new SRAM architectures as well as new forms of DRAM and other new memory technologies. Because we have limited experience developing IC products other than Very Fast SRAMs, any efforts by us to introduce new products based on a new memory technology may not be successful and our business may suffer.

Intellectual Property

Our ability to compete successfully depends, in part, upon our ability to protect our proprietary technology and information. We rely on a combination of patents, copyrights, trademarks, trade secret

laws, non-disclosure and other contractual arrangements and technical measures to protect our intellectual property. We currently hold three United States patents, expiring between November 2022 and April 2023, and have ten patent applications pending. We do not consider our existing patents to be materially important to our business, and we cannot assure you that any patents will issue as a result of our pending applications or that any patents issued will be valuable to our business. We believe that factors such as the technological and creative skills of our personnel and the success of our ongoing product development efforts are more important than our patent portfolio in maintaining our competitive position. We generally enter into confidentiality or license agreements with our employees, distributors, customers and potential customers and limit access to our proprietary information. Our intellectual property rights, if challenged, may not be upheld as valid, may not be adequate to prevent misappropriation of our technology or may not prevent the development of competitive products. Additionally, we may not be able to obtain patents or other intellectual property protection in the future. Furthermore, the laws of certain foreign countries in which our products are or may be developed, manufactured or sold, including various countries in Asia, may not protect our products or intellectual property rights to the same extent as do the laws of the United States and thus make the possibility of piracy of our technology and products more likely in these countries.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights, which have resulted in significant and often protracted and expensive litigation. We or our foundry from time to time are notified of claims that we may be infringing patents or other intellectual property rights owned by third parties. We have been subject to intellectual property claims in the past and we may be subject to additional claims and litigation in the future. Litigation by or against us relating to allegations of patent infringement or other intellectual property matters could result in significant expense to us and divert the efforts of our technical and management personnel, whether or not such litigation results in a determination favorable to us. In the event of an adverse result in any such litigation, we could be required to pay substantial damages, cease the manufacture, use and sale of infringing products, expend significant resources to develop non-infringing technology, discontinue the use of certain processes or obtain licenses to the infringing technology. Licenses may not be offered or the terms of any offered licenses may not be acceptable to us. If we fail to obtain a license from a third party for technology used by us, we could incur substantial liabilities and be required to suspend the manufacture of products or the use by our foundry of certain processes.

Pending Litigation

On October 23, 2006, we were served with a civil antitrust complaint filed by Reclaim Center, Inc. and other plaintiffs in the United States District Court for the Northern District of California against the Company and a number of other semiconductor companies. The complaint was filed on behalf of a purported class of indirect purchasers of SRAM products throughout the United States. The complaint alleges that the defendants conspired to raise the price of SRAM in violation of Section 1 of the Sherman Act, the California Cartwright Act, and several other state antitrust, unfair competition and consumer protection statutes. Shortly thereafter, a number of similar complaints were filed by other plaintiffs in various jurisdictions on behalf of purported classes of both direct and indirect purchasers. We have been served in some but not all of these subsequent actions. Many of these cases have been transferred by the Judicial Panel on Multidistrict Litigation to the Northern District of California. We believe that we have meritorious defenses to the allegations in the complaints, and we intend to defend these lawsuits vigorously. However, the litigation is in the preliminary stage and we cannot predict its outcome. The litigation process is inherently uncertain. Multidistrict antitrust litigation is particularly complex and can extend for a protracted time, which can substantially increase the cost of such litigation. The defense of these lawsuits is also expected to divert the efforts and attention of some of our key management and technical personnel. As a result, our defense of this litigation, regardless of its eventual outcome, will likely be costly and time consuming. Should the outcome of the litigation be

adverse to us, we could be required to pay significant monetary damages, which could adversely affect our business, financial condition, operating results and cash flows.

Employees

As of December 31, 2006, we had 100 full-time employees, including 42 engineers, of which 21 are in research and development and 23 have PhD or MS degrees, 16 employees in sales and marketing, eight employees in general and administrative capacities and 52 employees in manufacturing. Of these employees, 36 are based in our Santa Clara facility and 42 are based in our Taiwan facility. We believe that our future success will depend in large part on our ability to attract and retain highly-skilled, engineering, managerial, sales and marketing personnel. Our employees are not represented by any collective bargaining unit, and we have never experienced a work stoppage. We believe that our employee relations are good.

Facilities

Our executive offices, our principal administration, marketing and sales operations and a portion of our research and development operations are located in approximately 20,300 square feet of space in Santa Clara, California, which we occupy under a lease expiring in May 2010. We believe that our Santa Clara facility is adequate for our needs for the foreseeable future. In addition, we lease approximately 15,250 square feet in Taiwan to support our manufacturing activities. We also lease space in Georgia and Texas. The aggregate annual gross rent for our facilities was approximately $537,000 in fiscal 2006.

Board of Directors

Our business and affairs are organized under the direction of our Board of Directors, which currently consists of five members. The primary responsibilities of our Board of Directors are to provide oversight, strategic guidance, counseling and direction to our management. Each director will be subject to election at each annual meeting of stockholders.

In January 2007, our Board of Directors undertook a review of the independence of the directors and considered whether any director had a material relationship with us that could compromise his ability to exercise independent judgment in carrying out his responsibilities. As a result of this review, our Board of Directors determined that Messrs. Chen, Lu and Tang are "independent directors" as defined under the rules of Nasdaq.

Committees of the Board of Directors

Our Board of Directors has established three standing committees: an audit committee, a compensation committee, and a nominating and corporate governance committee. Each member of each of the foregoing committees is independent as defined under the rules of the Nasdaq Global Market.

Audit Committee. The audit committee oversees, reviews and evaluates our financial statements, accounting and financial reporting processes, internal control functions and the audits of our financial statements. The audit committee is responsible for the appointment, compensation, retention and oversight of our independent auditors. The members of our audit committee are Hsiang-Wen Chen and Ruey L. Lu. Each member of our audit committee satisfies the independence requirements of Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, as amended.

The composition of our audit committee does not currently comply with the applicable requirements of the Nasdaq and SEC rules and regulations in that we have two rather than three members of such committee. We anticipate that within one year of the date of this offering, the time required by applicable Nasdaq listing requirements, we will be in compliance with such requirements. While each member of the audit committee is "financially sophisticated," as defined in the Nasdaq listing requirements, our Board of Directors has determined that there is currently no "audit committee financial expert," as defined in SEC rules, serving on the audit committee. We are conducting a search for a person who qualifies as an audit committee financial expert who is willing to serve as a director and as a member of our audit committee.

Compensation Committee. The compensation committee reviews and makes recommendations to our Board of Directors concerning the compensation and benefits of our executive officers and directors, administers our stock option and employee benefits plans, and reviews general policy relating to compensation and benefits. The members of our compensation committee are Hsiang-Wen Chen and Ruey L. Lu.

Nominating and Corporate Governance Committee. The nominating and corporate governance committee identifies prospective board candidates, recommends nominees for election to our Board of Directors, develops and recommends board member selection criteria, considers committee member qualification, recommends corporate governance principles to the Board of Directors, and provides oversight in the evaluation of the Board of Directors and each committee. The members of our nominating and corporate governance committee are Hsiang-Wen Chen and Ruey L. Lu.

Director Compensation

Our directors do not currently receive cash compensation for their services as directors or members of committees of the Board of Directors. We plan to adopt a policy for the payment of cash compensation to our non-employee directors, to become effective upon the completion of this offering. Annual compensation for each non-employee director will be $15,000 per year. In-person attendance at Board of Directors meetings or committee meetings will be compensated at $1,500 per meeting.

The value of unexercised in-the-money options at March 31, 2006 is determined by multiplying the number of shares issued or issuable upon exercise of the option by the difference between the initial public offering price of $5.50 per share and the per share option exercise price.

Stock Plans

1997 Stock Plan

In January 1997, our Board of Directors adopted and our stockholders approved the 1997 Stock Plan, or the 1997 Plan. A total of 8,450,000 shares of common stock were reserved for issuance under this plan. As of December 31, 2006, there were outstanding under the 1997 Plan options to purchase 1,425,327 shares of common stock, at a weighted average exercise price of $1.56 per share. The 1997 Plan was terminated by the Board in October 2000, and no additional options may be granted under the 1997 Plan. However, options granted under the 1997 Plan prior to its termination will remain outstanding until they are either exercised or expire.

Under the 1997 Plan, our employees and consultants, and those of any parent or subsidiary of ours, were eligible to receive nonstatutory stock options and stock purchase rights. Employees were also eligible to receive "incentive stock options," within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code. This plan is administered by our Board of Directors. Subject to the provisions of the 1997 Plan, the Board determined in its discretion the persons to whom and the times at which options and stock purchase rights were granted, the sizes of such awards, and all of their terms and conditions. All option and restricted stock awards are evidenced by a written agreement between us and the optionee. The Board may amend or reprice any option. The Board has the authority to construe and interpret the terms of the 1997 Plan and awards granted under it.

The exercise price of nonstatutory stock options granted under the 1997 Plan must be at least 85% of the fair market value of a share of our common stock on the date of grant. The exercise price of incentive stock options cannot be less than 100% of the fair market value of a share of our common stock on the date of grant. In the case of any options granted to a person who owns stock possessing more than 10% of the total combined voting power of all classes of our stock or of any parent or subsidiary corporation, the exercise price cannot be less than 110% of such fair market value. The term of an option cannot exceed 10 years, or 5 years for incentive stock options granted to 10% stockholders. An option generally remains exercisable for the period stated in the applicable option agreement (not less than 30 days) following the optionee's termination of service, except that if service terminates as a result of the optionee's death or disability, the option will remain exercisable for 12 months, but in any event not beyond the expiration of its term. Shares subject to options granted under the 1997 Plan generally vest, conditioned upon the participant's continued service, over a period of four years, although the Board may specify a different period for a particular grant.

Stock purchase rights generally are granted subject to a repurchase option in favor of us that lapses in accordance with a vesting schedule, which vesting is not less than 20% per year over five years. A stock purchase agreement will contain the particular terms of the award, which terms shall be determined by the Board.

In the event of a merger, the acquiring or successor corporation may assume or substitute substantially equivalent options and stock purchase rights for the outstanding options or rights granted under the 1997 Plan. If the acquiring or successor corporation elects not to assume or substitute for outstanding options and stock purchase rights granted under the 1997 Plan, shares subject to the options and rights will terminate.

2000 Stock Option Plan

In October 2000, our Board of Directors adopted and our stockholders subsequently approved the 2000 Stock Option Plan, or the 2000 Plan. A total of 3,500,000 shares of common stock have been reserved for issuance under this plan. As of December 31, 2006, there were outstanding under the 2000 Plan options to purchase 2,923,542 shares of common stock, at a weighted average exercise price of $4.48 per share. As of December 31, 2006, a total of 559,897 shares of common stock remained available for future option grants under the 2000 Plan. The 2000 Plan will terminate and no further shares will be issued thereunder upon stockholder approval of the 2007 Equity Incentive Plan described below. However, options granted under the 2000 Plan prior to its termination will remain outstanding until they are either exercised or expire.

Under the 2000 Plan, our employees, directors and consultants, and those of any parent or subsidiary of ours, are eligible to receive nonstatutory stock options. Employees are also eligible to receive "incentive stock options," within the meaning of Section 422 of the Internal Revenue Code. This plan is administered by our Board of Directors. Subject to the provisions of the 2000 Plan, the Board determines in its discretion the persons to whom and the times at which options are granted, the types and sizes of such options, and all of their terms and conditions. All options are evidenced by a written agreement between us and the optionee. The Board may amend, modify, cancel, extend or renew any option, grant a new option in substitution for any option, waive any restrictions or conditions applicable to any option, and accelerate, continue, extend or defer the vesting of any option. The Board has the authority to construe and interpret the terms of the 2000 Plan and options granted under it.

The exercise price of nonstatutory stock options granted under the 2000 Plan must be at least 85% of the fair market value of a share of our common stock on the date of grant. The exercise price of incentive stock options cannot be less than 100% of the fair market value of a share of our common stock on the date of grant. In the case of any options granted to a person who owns stock possessing more than 10% of the total combined voting power of all classes of our stock or of any parent or

subsidiary corporation, the exercise price cannot be less than 110% of such fair market value. The term of an option cannot exceed 10 years, or 5 years for incentive stock options granted to 10% stockholders. Unless a longer period is provided by the Board, an option generally remains exercisable for three months following the optionee's termination of service, except that if service terminates as a result of the optionee's death or disability, the option generally remains exercisable for 12 months, but in any event not beyond the expiration of its term. Shares subject to options granted under the 2000 Plan generally vest, conditioned upon the participant's continued service, over a period of four years, with 25% vesting per year.

In the event of a change in control, the acquiring or successor corporation may assume or substitute substantially equivalent options for the outstanding options granted under the 2000 Plan. If the acquiring or successor corporation elects not to assume or substitute for outstanding options granted under the 2000 Plan, shares subject to the options will accelerate and become vested and exercisable and vested ten days prior to the date of the change in control in such amounts as determined by the Board and set forth in the participant's stock option agreement. On completion of a change in control all outstanding options will terminate to the extent not exercised or assumed by the acquiring or successor corporation.

2007 Equity Incentive Plan

Our 2007 equity incentive plan, or the Equity Plan, was approved by our Board of Directors in January 2007 and will be effective upon its approval by our stockholders, currently anticipated in March 2007.

A total of 3,000,000 shares of our common stock are initially authorized and reserved for issuance under the Equity Plan. This reserve will automatically increase on April 1, 2008 and each subsequent anniversary through 2017, by an amount equal to the smaller of (a) five percent (5%) of the number of shares of stock issued and outstanding on the immediately preceding March 31, or (b) a lesser amount determined by the Board. Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the Equity Plan and in outstanding awards to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in our capital structure. Shares subject to awards which expire or are cancelled or forfeited will again become available for issuance under the Equity Plan. The shares available will not be reduced by awards settled in cash or by shares withheld to satisfy tax withholding obligations. Only the net number of shares issued upon the exercise of stock appreciation rights or options exercised by means of a net exercise or by tender of previously owned shares will be deducted from the shares available under the Equity Plan.

Awards may be granted under the Equity Plan to our employees, including officers, directors, or consultants or those of any present or future parent or subsidiary corporation or other affiliated entity. While we may grant incentive stock options only to employees, we may grant nonstatutory stock options, stock appreciation rights, restricted stock purchase rights or bonuses, restricted stock units, performance shares, performance units and cash-based awards or other stock-based awards to any eligible participant. Non-employee director awards will be granted only to members of our Board of Directors who, at the time of grant, are not employees. Deferred compensation awards may be granted only to officers, directors and select members of management or highly compensated employees.

Only members of the Board of Directors who are not employees at the time of grant are eligible to participate in the nonemployee director awards component of the Equity Plan. The Board or the compensation committee shall set the amount and type of nonemployee director awards to be awarded on a periodic, non-discriminatory basis. Nonemployee director awards may be granted in the form of nonstatutory stock options, stock appreciation rights, restricted stock awards and restricted stock unit awards. Subject to adjustment for changes in our capital structure, no nonemployee director may be awarded, in any fiscal year, one or more nonemployee director awards for more than 2,000 shares.

However, the annual limit may be increased by the following additions: (i) an additional 10,000 shares in the fiscal year in which the nonemployee director is first appointed or elected to the Board, (ii) an additional 2,000 shares in any fiscal year in which the nonemployee director is serving as the chairman or lead director of the Board, (iii) an additional 1,000 shares in any fiscal year for each committee of the Board on which the nonemployee director is then serving other than as chairman of the committee, and (iv) an additional 2,000 shares in any fiscal year for each committee of the Board on which the nonemployee director is then serving as chairman of the committee.

In the event of a change in control as described in the Equity Plan, the acquiring or successor entity may assume or continue all or any awards outstanding under the Equity Plan or substitute substantially equivalent awards. Any awards which are not assumed or continued in connection with a change in control or exercised or settled prior to the change in control will terminate effective as of the time of the change in control. The administrator may provide for the acceleration of vesting of any or all outstanding awards upon such terms and to such extent as it determines, except that the vesting of all nonemployee director awards will automatically be accelerated in full. The Equity Plan also authorizes the administrator, in its discretion and without the consent of any participant, to cancel each or any outstanding award denominated in shares upon a change in control in exchange for a payment to the participant with respect to each vested share subject to the cancelled award of an amount equal to the excess of the consideration to be paid per share of common stock in the change in control transaction over the exercise price per share, if any, under the award.

2007 Employee Stock Purchase Plan

Our 2007 Employee Stock Purchase Plan, or the Purchase Plan, was adopted by our Board of Directors in January 2007 and is expected to be approved by our stockholders in March 2007. The Purchase Plan will become effective upon the completion of this offering.

A total of 500,000 shares of our common stock are initially authorized and reserved for sale under the Purchase Plan. In addition, the Purchase Plan provides for an automatic annual increase in the number of shares available for issuance under the plan on April 1 of each year beginning in 2008 and continuing through and including April 1, 2017 equal to the lesser of (1) one percent (1%) of our then issued and outstanding shares of common stock on the immediately preceding March 31, (2) 250,000 shares or (3) a number of shares as our Board may determine. Appropriate adjustments will be made in the number of authorized shares and in outstanding purchase rights to prevent dilution or enlargement of participants' rights in the event of a stock split or other change in our capital structure. Shares subject to purchase rights which expire or are canceled will again become available for issuance under the Purchase Plan.

Our employees and employees of any parent or subsidiary corporation designated by the administrator are eligible to participate in the Purchase Plan if they are customarily employed by us for more than 20 hours per week and more than 5 months in any calendar year. However, an employee may not be granted a right to purchase stock under the Purchase Plan if: (1) the employee immediately after such grant would own stock possessing 5% or more of the total combined voting power or value of all classes of our capital stock or of any parent or subsidiary corporation, or (2) the employee's rights to purchase stock under all of our employee stock purchase plans would accrue at a rate that exceeds $25,000 in value for each calendar year of participation in such plans.

The Purchase Plan is implemented through a series of sequential offering periods, generally six (6) months in duration beginning on the first trading day on or after May 1 and November 1 of each year, except that the first offering period will commence on the effective date of the Purchase Plan and will end on October 31, 2007. The administrator is authorized to establish additional or alternative sequential or overlapping offering periods and offering periods having a different duration or different starting or ending dates, provided that no offering period may have a duration exceeding 27 months.

Amounts accumulated for each participant are used to purchase shares of our common stock at the end of each offering period at a price generally equal to 85% of the lower of the fair market value of our common stock at the beginning of an offering period or at the end of the offering period. Prior to commencement of an offering period, the administrator is authorized to reduce, but not increase, this purchase price discount for that offering period, or, under circumstances described in the Purchase Plan, during that offering period. The maximum number of shares a participant may purchase in any six-month offering period is the lesser of (i) that number of shares determined by multiplying (x) 1,000 shares by (y) the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole share or (ii) that number of whole shares determined by dividing (x) the product of $2,083.33 and the number of months (rounded to the nearest whole month) in the offering period and rounding to the nearest whole dollar by (y) the fair market value of a share of our common stock at the beginning of the offering period. Prior to the beginning of any offering period, the administrator may alter the maximum number of shares that may be purchased by any participant during the offering period or specify a maximum aggregate number of shares that may be purchased by all participants in the offering period. If insufficient shares remain available under the plan to permit all participants to purchase the number of shares to which they would otherwise be entitled, the administrator will make a pro rata allocation of the available shares. Any amounts withheld from participants' compensation in excess of the amounts used to purchase shares will be refunded, without interest.

In the event of a change in control, an acquiring or successor corporation may assume our rights and obligations under the Purchase Plan. If the acquiring or successor corporation does not assume such rights and obligations, then the purchase date of the offering periods then in progress will be accelerated to a date prior to the change in control.

Simplified Employee Pension Plan

We have adopted a Simplified Employee Pension Plan which is intended to satisfy the requirements under Section 408 of the Internal Revenue Code. Under the terms of this plan, we may, but are not required, to make discretionary contributions to each participant's individual retirement account. Contributions to the plan are generally deductible by us when made, and are not taxable to participants until distributed. Pursuant to the plan, participants may direct the trustees to invest their individual retirement accounts.

Indemnification of Directors and Executive Officers and Limitation of Liability

As permitted by the Delaware General Corporation Law, our certificate of incorporation provides that our directors shall not be personally liable for monetary damages to us or our stockholders for a breach of fiduciary duty as a director, except liability for:

•: a breach of the director's duty of loyalty to us or our stockholders;
•: acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;
•: an act related to an unlawful stock repurchase or redemptions or payments of dividends; or
•: transactions from which the director derived an improper personal benefit.

These limitations of liability do not apply to liabilities arising under the federal securities laws and do not affect the availability of equitable remedies such as injunctive relief or rescission.

As permitted by the Delaware General Corporation Law, our bylaws provide that:

•: we are required to indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions where indemnification is not permitted by applicable law;
•: we are required to advance expenses, as incurred, to our directors and officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; and
•: the rights provided in the bylaws are not exclusive.

If Delaware law is amended to authorize corporate action further eliminating or limiting the personal liability of a director, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law, as so amended. Our amended and restated certificate of incorporation does not eliminate a director's duty of care and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief remain available under Delaware law. Our amended and restated certificate of incorporation does not affect a director's responsibilities under any other laws, such as the federal securities laws or state or federal environmental laws.

We have entered into separate indemnification agreements with each of our directors and officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements may require us, among other things, to indemnify our officers and directors against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also may require us to advance any expenses incurred by the directors or officers as a result of any proceeding against them as to which they could be indemnified and to obtain directors' and officers' insurance if available on reasonable terms. We believe that these agreements and these provisions in our bylaws and certificate of incorporation are necessary to attract and retain qualified persons as officers and directors. We also intend to maintain directors' and officers' liability insurance.

At present, there is no pending litigation or proceeding involving any of our directors, officers, employees or agents where indemnification by us is sought. In addition, we are not aware of any threatened litigation or proceeding, which may result in a claim for indemnification.

DESCRIPTION OF CAPITAL STOCK

Upon the completion of this offering, our authorized capital stock will consist of 150,000,000 shares of common stock, $0.001 par value per share, and 5,000,000 shares of preferred stock, $0.001 par value per share.

The following is a summary of the material terms of our common stock and preferred stock. Please see our certificate of incorporation and bylaws filed as an exhibits to the registration statement of which this prospectus is a part, for more detailed information.

Common Stock

As of December 31, 2006, there were 21,402,829 shares of our common stock outstanding held of record by 136 stockholders, assuming the conversion of our outstanding redeemable convertible preferred stock into common stock. The holders of our common stock are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Upon the completion of this offering, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election. Subject to preferences applicable to any outstanding preferred stock, holders of common stock are entitled to receive ratably any dividends declared by the Board. In the event of a liquidation, dissolution or winding up of the company, holders of common stock are entitled to share ratably in the assets remaining after payment of liabilities and the liquidation preferences of any outstanding preferred stock. Holders of our common stock have no preemptive, conversion or redemption rights. Each outstanding share of common stock is, and all shares of common stock to be outstanding upon the completion of this offering will be, fully paid and non-assessable.

Preferred Stock

Immediately prior to the completion of this offering, all outstanding shares of our outstanding redeemable convertible preferred stock will be converted into an aggregate of 15,120,168 shares of common stock provided that the aggregate offering price of the shares offered in this offering equals or exceeds $10,000,000. Following the completion of the offering, 5,000,000 shares of undesignated preferred stock will be authorized for issuance. Our Board of Directors will have the authority, without further action by our stockholders, to issue preferred stock in one or more series. In addition, the Board may fix the rights, preferences and privileges of any preferred stock it determines to issue. Any or all of these rights may be superior to the rights of the common stock. Preferred stock could thus be issued quickly with terms calculated to delay or prevent a change in control of our company or to make removal of management more difficult. Additionally, the issuance of preferred stock may decrease the market price of our common stock. At present, we have no plans to issue any shares of preferred stock.

Registration Rights

None of our stockholders has any registration rights.

Antitakeover Provisions

Delaware Law

We will be subject to Section 203 of the Delaware General Corporation Law regulating corporate takeovers, which prohibits a Delaware corporation from engaging in any business combination with an "interested stockholder," unless:

•: prior to the date of the transaction, the Board of Directors of the corporation approved either the business combination or the transaction, which resulted in the stockholder becoming an interested stockholder;

•: the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding (a) shares owned by persons who are directors and also officers, and (b) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
•: on or subsequent to the date of the transaction, the business combination is approved by the Board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66²/3% of the outstanding voting stock which is not owned by the interested stockholder.

Except as otherwise specified in Section 203, an "interested stockholder" is defined to include:

•: any person that is the owner of 15% or more of the outstanding voting securities of the corporation, or is an affiliate or associate of the corporation and was the owner of 15% or more of the outstanding voting stock of the corporation at any time within three years immediately prior to the date of determination and
•: the affiliates and associates of any such person.

Certificate of Incorporation and Bylaws

Following the completion of this offering, our certificate of incorporation and bylaws will provide that:

•: no action can be taken by stockholders except at an annual or special meeting of the stockholders called in accordance with our bylaws, and stockholders may not act by written consent;
•: the approval of holders of two-thirds of the shares entitled to vote at an election of directors will be required to adopt, amend or repeal our bylaws or amend or repeal the provisions of our certificate of incorporation regarding the election and removal of directors and the ability of stockholders to take action;
•: our Board of Directors will be expressly authorized to make, alter or repeal our bylaws;
•: our Board of Directors will be authorized to issue preferred stock without stockholder approval;
•: directors may only be removed for cause by the holders of two-thirds of the shares entitled to vote at an election of directors; and
•: we will indemnify officers and directors against losses that may incur as a result of investigations and legal proceedings resulting from their services to us, which may include services in connection with takeover defense measures.

These provisions may make it more difficult for stockholders to take specific corporate actions and could have the effect of delaying or preventing a change in control of our company.

Transfer Agent and Registrar

The transfer agent and registrar for the common stock is Computershare Limited.

Nasdaq Global Market Listing

Our common stock has been approved for listing on the Nasdaq Global Market under the symbol "GSIT."

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has not been a public market for our common stock. Future sales of substantial amounts of our common stock in the public market, or the possibility of these sales, could adversely affect the trading price of our common stock.

Upon completion of this offering, we will have outstanding 27,533,940 shares of common stock, assuming no exercise of outstanding options to purchase common stock after December 31, 2006. Of these shares, the 6,131,111 shares sold in this offering will be freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by our "affiliates," as defined in Rule 144 under the Securities Act, which would be subject to the limitations and restrictions described below.

The remaining 21,402,829 shares of common stock outstanding upon completion of this offering will be "restricted securities" as defined in Rule 144. These securities may be sold in the public market only if registered or if they qualify for an exemption from registration under Rules 144 or 701 under the Securities Act, which are summarized below. Sales of these restricted securities in the public market, or the availability of these shares for sale, could adversely affect the trading price of our common stock.

Holders of approximately 21,181,268 of these restricted securities, including all of our officers and directors and the entities affiliated with them, have entered into lock-up agreements providing that, subject to limited exceptions, they will not sell, directly or indirectly, any common stock without the prior consent of Needham & Company, LLC for a period of 180 days from the date of this prospectus. In addition, the 180 day period may be extended for up to 34 additional days under certain circumstances. See "Underwriting."

The number of restricted securities that will be available for sale in the public market, subject in some cases to the volume limitations and other restrictions of Rule 144, will be as follows:

•: approximately 221,561 shares will be eligible for immediate sale as of the date of this prospectus; and
•: approximately 21,181,268 additional shares will be eligible for sale beginning 180 days after the date of this prospectus upon expiration of the lock-up agreements described above.

Shares issued upon exercise of options granted by us prior to the date of this prospectus will be available for sale in the public market under Rule 701 of the Securities Act. Rule 701 permits resales of these shares in reliance upon Rule 144 but without compliance with various restrictions, including the holding period requirement, imposed under Rule 144. In general, under Rule 144, beginning 90 days after the date of this prospectus, a person (or persons whose shares are aggregated) who has beneficially owned restricted securities for at least one year would be entitled to sell within any three-month period a number of shares not to exceed the greater of (1) one percent of the then outstanding shares of common stock or (2) the average weekly trading volume of our common stock during the four calendar weeks preceding the filing of a Form 144 with respect to the sale. Sales under Rule 144 are also subject to manner of sale and notice requirements, as well as to the availability of current public information about us. Under Rule 144(k), a person who is not deemed to have been an affiliate at any time during the 90 days preceding a sale and who has beneficially owned the shares proposed to be sold for at least two years is entitled to sell the shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144.

As of December 31, 2006, options to purchase an aggregate of 4,348,869 shares of common stock were outstanding under our stock option plans. We intend to file registration statements on Form S-8 under the Securities Act approximately 90 days after the date of this prospectus to register an aggregate of approximately 3,500,000 shares of common stock issued or reserved for issuance under its stock option plans and employee stock purchase plan. Shares of common stock issued under the foregoing plans, after the filing of related registration statements, will be freely tradable in the public market, subject in the case of the holders to the Rule 144 limitations applicable to our affiliates, lock-up agreements with the underwriters and vesting restrictions imposed by us.

UNDERWRITING

We and the selling stockholders have entered into an underwriting agreement with the underwriters named below. Needham & Company, LLC and W.R. Hambrecht + Co., LLC are acting as joint book running managers of this offering and, together with Robert W. Baird & Co. Incorporated and Stanford Group Company, are acting as representatives of the underwriters. The underwriters' obligations are several, which means that each underwriter is required to purchase a specific number of shares, but is not responsible for the commitment of any other underwriter to purchase shares. Subject to the terms and conditions of the underwriting agreement, each underwriter has severally agreed to purchase from us and the selling stockholders the number of shares of common stock set forth opposite its name below.

Underwriter		Number of Shares
Needham & Company, LLC		2,452,444
WR Hambrecht + Co., LLC		2,452,444
Robert W. Baird & Co. Incorporated		919,667
Stanford Group Company		306,556

	Total	6,131,111

The underwriting agreement provides that the underwriters are obligated to purchase all the shares of common stock in the offering if any are purchased, other than those shares covered by the over-allotment option described below.

The underwriting agreement provides that we and the selling stockholders will indemnify the underwriters against certain liabilities that may be incurred in connection with this offering, including liabilities under the Securities Act, or to contribute payments that the underwriters may be required to make in respect thereof.

The selling stockholders have granted an option to the underwriters to purchase up to 919,667 additional shares of common stock at the public offering price per share, less the underwriting discount, set forth on the cover page of this prospectus. This option is exercisable during the 30-day period after the date of this prospectus. The underwriters may exercise this option only to cover over-allotments made in connection with this offering. If this option is exercised, each of the underwriters will purchase approximately the same percentage of the additional shares as the number of shares of common stock to be purchased by that underwriter, as shown in the table above, bears to the total shown.

The representatives have advised us and the selling stockholders that the underwriters propose to offer the shares of common stock to the public at the public offering price per share set forth on the cover page of this prospectus. The underwriters may offer shares to securities dealers, who may include the underwriters, at that public offering price less a concession of up to $0.231 per share. After the offering to the public, the offering price and other selling terms may be changed by the representatives.

The following table shows the per share and total underwriting discount to be paid to the underwriters by us and the selling stockholders. These amounts are shown assuming both no exercise and full exercise of the underwriters' option to purchase additional shares.

	Total
	Per Share		No Exercise		Full Exercise
Paid by GSI Technology, Inc.	$	0.385	$	2,360,478	$	2,360,478
Paid by selling stockholders		0.385		—		354,072

We will pay the expenses of the offering on behalf of the selling stockholders, excluding the underwriting discount. We estimate that the total incremental expenses of the selling stockholders related to the offering, excluding the underwriting discount, will be approximately $30,000.

We have agreed not to offer, sell, contract to sell, pledge, grant options to purchase, or otherwise dispose of any shares of our common stock or securities exchangeable for or convertible into our common stock for a period of 180 days after the date of this prospectus without the prior written consent of the joint book-running managers. This agreement does not apply to any existing employee benefit plans. Our directors, officers, and the selling stockholders and other stockholders, who collectively hold in the aggregate 21,181,268 shares of common stock, have agreed not to, directly or indirectly, sell, hedge, or otherwise dispose of any shares of common stock (other than shares sold upon exercise of the underwriters' over-allotment option), options to acquire shares of common stock or securities exchangeable for or convertible into shares of common stock, for a period of 180 days after the date of this prospectus without the prior written consent of Needham & Company, LLC. However, in the event that either (1) during the last 17 days of the "lock-up" period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the "lock-up" period, we announce that we will release earnings results during the 16-day period beginning on the last day of the "lock-up" period, then in either case the expiration of the "lock-up" will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless the joint book-running managers waive, in writing, such an extension. A transfer of securities to a family member, trust, affiliate, partner or member of such person, or as a bona fide gift, may be made, provided the transferee agrees to be bound in writing by the above restrictions prior to the transfer.

The representatives have informed us that they do not expect sales by the underwriters to discretionary accounts to exceed 5% of the total number of shares offered.

In connection with this offering, Needham & Company, LLC, on behalf of the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock. Specifically, the underwriters may over-allot in connection with this offering by selling more shares than are set forth on the cover page of this prospectus. This creates a short position in our common stock for their own account. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. To close out a short position or to stabilize the price of our common stock, the underwriters may bid for, and purchase, common stock in the open market. The underwriters may also elect to reduce any short position by exercising all or part of the over-allotment option. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter or dealer repays selling concessions allowed to it for distributing our common stock in this offering because the underwriters repurchase that stock in stabilizing or short covering transactions.

Finally, the underwriters may bid for, and purchase, shares of our common stock in market making transactions.

These activities may stabilize or maintain the market price of our common stock at a price that is higher than the price that might otherwise exist in the absence of these activities. The underwriters are not required to engage in these activities, and may discontinue any of these activities at any time without notice. These transactions may be effected on the Nasdaq Global Market, in the over-the-counter market, or otherwise.

Prior to this offering, there has been no public market for our common stock. Consequently, the initial public offering price will be determined by negotiations among us, the selling stockholders, and the representatives. Among the factors to be considered in these negotiations are:

•: our history and prospects and the history and prospect of the industry in which we compete;
•: an assessment of our management;
•: our past and present operations;
•: our past and present earnings and the trend of those earnings;
•: our prospects for future earnings;
•: our present state of development;
•: the general condition of the securities markets at the time of the offering; and
•: the market prices of and demand for publicly traded common stock of comparable companies in recent periods.

LEGAL MATTERS

The validity of the common stock offered hereby will be passed upon for us by DLA Piper US LLP, East Palo Alto, California. Certain legal matters relating to the offering will be passed upon for the underwriters by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto, California.

In addition, in our opinion, the accompanying financial statement schedule presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements.

We believe that our audits provide a reasonable basis for our opinion.

GSI TECHNOLOGY, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

GSI Technology, Inc. (the "Company") was incorporated in California in March 1995 and reincorporated in Delaware on June 9, 2004. The Company is a provider of "Very Fast" SRAM products that are incorporated primarily in high-performance networking and telecommunications equipment, such as routers, switches, wide area network infrastructure equipment, wireless base stations and network access equipment. In addition, the Company serves the ongoing needs of the military, industrial, test equipment and medical markets for high-performance SRAMs.

Accounting principles

The consolidated financial statements and accompanying notes were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP").

Basis of consolidation

The consolidated financial statements include the accounts of the Company's two wholly-owned subsidiaries, GSI Technology Holdings, Inc. and GSI Technology (BVI), Inc. All significant inter-company transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates are inherent in the preparation of the consolidated financial statements and include revenue recognition, obsolete and excess inventory, the valuation allowance on deferred tax assets, the valuation of equity instruments and stock-based compensation. Actual results could differ from those estimates.

Risk and uncertainties

The Company buys all of its wafers, an integral component of its products, from a single supplier and is also dependent on independent suppliers to assemble and test its products. During the years ended March 31, 2004, 2005 and 2006 and for the nine month period ended December 31, 2006, all of the Company's wafers were supplied by Taiwan Semiconductor Manufacturing Company Limited, or TSMC. If this supplier fails to satisfy the Company's requirements on a timely basis at competitive prices, the Company could suffer manufacturing delays, a possible loss of revenues, or higher cost of revenues, any of which could adversely affect operating results.

A majority of the Company's net revenues come from sales to customers in the networking and telecommunications equipment industry. A decline in demand in this industry could have a material adverse affect on the Company's operating results and financial condition.

Because much of the manufacturing and testing of the Company's products is conducted in Taiwan, its business performance may be affected by changes in Taiwan's political, social and economic environment. For example, any political instability resulting from the relationship among the United States, Taiwan and the People's Republic of China could damage the Company's business. Moreover, the role of the Taiwanese government in the Taiwanese economy is significant. Taiwanese policies toward economic liberalization, and laws and policies affecting technology companies, foreign

F-7

investment, currency exchange rates, taxes and other matters could change, resulting in greater restrictions on the Company's and its suppliers' ability to do business and operate facilities in Taiwan. If any of these risks were to occur, the Company's business could be harmed.

Some of the Company's suppliers are located near fault lines. In the event of a major earthquake or other natural disaster near the facilities of any of these suppliers, the Company's business could be harmed.

Unaudited interim results

The accompanying consolidated balance sheet at December 31, 2006 and related consolidated statements of operations and of cash flows for the nine months ended December 31, 2005 and 2006 and the related consolidated statement of stockholders' equity for the nine months ended December 31, 2006, are unaudited. The interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company's results of operations and cash flows for the nine months ended December 31, 2005 and 2006 and financial position at December 31, 2006. The results for the nine months ended December 31, 2006 are not necessarily indicative of the results to be expected for the year ending March 31, 2007 or for any other interim period or for any other future year.

Unaudited pro forma stockholders' equity

Immediately prior to the consummation of the offering contemplated by this prospectus, and provided that the aggregate offering price of the shares offered hereby exceeds $10,000,000, all of the Company's redeemable convertible preferred stock will automatically convert to 15,120,168 shares of common stock, based on the shares of preferred stock outstanding at December 31, 2006. Unaudited pro forma stockholders' equity, as adjusted for the assumed conversion of the redeemable convertible preferred stock outstanding into 15,120,168 shares of the Company's common stock, is set forth on the accompanying consolidated balance sheet.

Revenue recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectibility is reasonably assured. Under these criteria, revenue from the sale of products is recognized upon shipment according to the Company's shipping terms, net of accruals for estimated sales returns and allowances based on historical experience. Sales to distributors are made under agreements allowing for returns or credits under certain circumstances. The Company defers recognition of revenue on sales to distributors until products are resold by the distributor. Sales to consignment warehouses, who purchase products from the Company for use by contract manufacturers, are recorded upon delivery to the contract manufacturer.

Cash and cash equivalents

Cash and cash equivalents include cash in demand accounts and highly liquid investments purchased with an original maturity of three months or less at the date of purchase, stated at cost, which approximates their fair market value.

F-8

Short-term investments

All of the Company's short-term investments are classified as available-for-sale. Short-term investments consist of auction rate securities with a contractual maturity in excess of five years. Even though the stated maturity dates of these investments may be one year or more beyond the balance sheet date, the Company has classified all auction rate securities as short-term investments. In accordance with Accounting Research Bulletin No. 43, Chapter 3A, Working Capital-Current Assets and Current Liabilities, the Company views its available-for-sale portfolio as available for use in its current operations. Based upon historical experience in the financial markets as well as the Company's specific experience with auction rate securities, the Company believes there is reasonable expectation of completing a successful auction in the next twelve month period. During its history of investing in these securities, the Company has not been unable to sell its holdings of these investments. Accordingly, the Company believes that the risk of non-redemption of these investments within a year is minimal. Investments are reported at fair value with unrealized gains and losses, net of related tax, as a component of other comprehensive income (loss). There were no unrealized gains or losses in relation to short-term investments for the years ended March 31, 2005 and 2006 or for the nine month period ended December 31, 2006 (unaudited) because of the frequent interest rate resetting nature of auction rate securities.

Restricted cash

At March 31, 2005 and 2006 and at December 31, 2006 (unaudited), restricted cash consists of certificates of deposit totaling $1,000,000 held with a financial institution as collateral for the Company's line of credit, and $159,000 at March 31, 2005 held with a Taiwan financial institution as security for any possible default of payment by the Company to its major supplier of wafers.

Concentration of credit risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents, short term investments and accounts receivable. The Company places its cash primarily in checking, certificate of deposit, and money market accounts with reputable financial institutions. The Company's accounts receivable are derived primarily from revenue earned from customers located in the U.S. and Asia. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. The Company maintains an allowance for doubtful accounts receivable based upon the expected collectibility of accounts receivable. The Company's write offs of accounts receivable were $49,000 and $29,000 for the years ended March 31, 2004 and 2005, respectively. There were no write offs in the year ended March 31, 2006. There were no write offs in the nine month periods ended December 31, 2005 and 2006 (unaudited).

In fiscal 2004, 2005 and 2006, sales to the Company's top 10 customers accounted for approximately 84%, 88% and 88% of net revenues, respectively. For the year ended March 31, 2004, three customers accounted for 27%, 18% and 14% of net revenues. At March 31, 2005, four customers accounted for 24%, 13%, 13% and 12% of accounts receivable and for the year then ended three customers accounted for 32%, 18% and 15% of net revenues. At March 31, 2006, three customers accounted for 28%, 17% and 12% of accounts receivable, and for the year then ended, three customers accounted for 30%, 27% and 10% of net revenues.

F-9

Inventories

Inventories are stated at the lower of cost or market, cost being determined on a weighted average basis. Inventory reserves are established when conditions indicate that the selling price could be less than cost due to physical deterioration, obsolescence, changes in price levels, or other causes. Reserves are established for excess inventory generally based on inventory levels in excess of 12 months of forecasted demand, as estimated by management, for each specific product.

During the years ended March 31, 2004, 2005 and 2006, the Company recorded reserves for excess, obsolete and other inventory related matters aggregating $846,000, $48,000 and $1,111,000, respectively. For the nine month periods ended December 31, 2005 and 2006, the Company recorded reserves for excess, obsolescence and other inventory related matters aggregating $933,000 (unaudited) and $328,000 (unaudited), respectively.

Property and equipment, net

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as presented below:

Software		3 years
Hardware and equipment		5 years
Furniture and fixtures		7 years

Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful lives of the assets or the remaining lease term of the respective assets. Gains or losses on disposals of property and equipment are recorded in operating expenses. Costs of repairs and maintenance are typically included as part of operating expenses unless they are incurred in relation to major improvements to existing property and equipment, at which time they are capitalized.

Impairment of long-lived assets

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that their net book value may not be recoverable. An impairment loss is recognized if the sum of the expected future cash flows (undiscounted and before interest) from the use of the assets is less than the net book value of the asset. The amount of the impairment loss, if any, will generally be measured as the difference between net book value of the assets and their estimated fair values. There were no impairment losses recognized during the years ended March 31, 2004, 2005 and 2006 and for the nine month period ended December 31, 2006 (unaudited).

Research and development

Research and development expenses are related to new product designs, including, salaries, contractor fees, and allocation of corporate costs and are charged to the statement of operations as incurred.

Income taxes

The Company accounts for income taxes under the liability method, whereby deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected

F-10

to affect taxable income. Valuation allowances are established when it is more likely than not that the deferred tax asset will not be realized.

Shipping and handling costs

The Company records costs related to shipping and handling in cost of revenues.

Advertising expense

Advertising costs are charged to expense in the period incurred. Advertising expense was $4,000 and $1,000 for the years ended March 31, 2004, and 2006, respectively. There was no advertising expense in the fiscal year ended March 31, 2005. Advertising expense for the nine month period ended December 31, 2006 was $4,000 (unaudited). There was no advertising expense during the nine month period ended December 31, 2005 (unaudited).

Foreign currency transactions

The U.S. dollar is the functional currency for all of the Company's foreign operations. Foreign currency transaction gains and losses, resulting from transactions denominated in currencies other than U.S. dollars are included in the statements of operations. These gains and losses have not been material for the fiscal years ended March 31, 2004, 2005 and 2006 or for the nine month period ended December 31, 2006 (unaudited).

Accounting for stock-based compensation

Prior to April 1, 2006, the Company accounted for employee stock options using the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees ("APB 25"), and Financial Accounting Standards Board ("FASB") Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB No. 25, and had adopted the disclosure-only provisions using the fair value method of SFAS No. 123, Accounting for Stock-Based Compensation ("SFAS 123"), and SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. In accordance with APB 25, the Company recognized compensation cost for options granted to the extent the exercise price was lower than the fair value of the underlying common stock on the date of grant. Prior to April 1, 2006, the Company allocated stock-based compensation costs using the straight line method and recognized the effect of forfeitures when they occurred.

On April 1, 2006, the Company adopted SFAS No. 123(R), Share-Based Payment ("SFAS 123(R)"), using the modified prospective transition method. Under this method, the Company's stock-based compensation costs recognized during the nine months ended December 31, 2006 were comprised of compensation costs for all share-based payment awards granted subsequent to April 1, 2006 and of compensation costs related to share-based payment awards that were unvested on April 1, 2006, based on their grant-date fair value estimated using the Black-Scholes option pricing model. Prior periods were not restated. As stock-based compensation expense recognized in the statement of operations for the nine months ended December 31, 2006 is based on options ultimately expected to vest, it has been reduced by the amount of estimated forfeitures.

The Company chose the straight-line method of allocating compensation cost over the requisite service period of the related award under SFAS 123(R). The Company calculated the expected term

F-11

based on the historical average period of time that options were outstanding as adjusted for expected changes in future exercise patterns, which, for options granted in the nine months ended December 31, 2006, resulted in an expected term of approximately four years (unaudited). The Company based its estimate of expected volatility on the estimated volatility of similar entities whose share prices are publicly available. The risk-free interest rate is based on the U.S. Treasury yields in effect at the time of grant for periods corresponding to the expected life of the options. The dividend yield is 0%, based on the fact that the Company has never paid dividends and has no present intention to pay dividends. Changes to these assumptions may have a significant impact on the results of operations.

The impact of adoption of SFAS 123(R) was to reduce income before tax by $809,000, net income by $787,000 and basic and diluted earnings per share by $0.13 and $0.03, respectively, for the nine months ended December 31, 2006 (unaudited). SFAS 123(R) requires cash flows, if any, resulting from the tax benefits from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) to be classified as financing cash flows. Adoption of FAS No. 123(R) did not have an impact on operating and financing cash flows because the Company did not have any excess tax benefits in the period of adoption.

Prior to the adoption of SFAS No. 123(R), the Company recognized forfeitures of unvested stock options as they occurred. Upon adoption of SFAS No. 123(R), the Company began estimating future forfeitures and recognizing the effect of such forfeitures on the grant date of the awards. SFAS No. 123(R) requires a one-time cumulative adjustment at the adoption date to record an estimate of future forfeitures on the unvested outstanding awards. Based on the Company's estimate of the impact of future forfeitures on the expense recognized for unvested options at the date of adoption, such one-time cumulative adjustment was determined to be immaterial.

Comprehensive income

The Company adopted Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("SFAS No. 130"). SFAS No. 130 establishes standards for reporting and displaying comprehensive income and its components. Comprehensive income is defined to include all changes in equity during a period except those resulting from investments by owners and distributions to owners. For the years ended March 31, 2004, 2005 and 2006 and the nine month periods ended December 31, 2005 and 2006 (unaudited), there were no other components of comprehensive income.

Recent accounting pronouncements

In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities," which permits entities to choose to measure eligible financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings at each subsequent reporting date. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the effect that the adoption of SFAS 159 will have on its consolidated financial position and results of operations.

In September 2006, the SEC issued Staff Accounting Bulletin No. 108, or SAB No. 108, Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements, which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement.

F-12

The Company will be required to adopt the provisions of SAB No. 108 in its fiscal year 2008. The Company does not believe the adoption of SAB No. 108 will have a material impact on its consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements. SFAS No. 157 establishes a framework for measuring fair value and expands disclosures about fair value measurements. The changes to current practice resulting from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. The Company will be required to adopt the provisions of SFAS No. 157 beginning with its fiscal quarter ending June 30, 2008. The Company does not believe the adoption of SFAS No. 157 will have a material impact on its consolidated financial position, results of operations or cash flows.

In July 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement 109 ("FIN 48"). FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). Under the Interpretation, the financial statements will reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts, but without considering time values. The Interpretation substantially changes the applicable accounting model and is likely to cause greater volatility in income statements as more items are recognized discretely within income tax expense. The Interpretation also revises disclosure requirements and introduces a prescriptive, annual, tabular roll-forward of the unrecognized tax benefits. The Interpretation requires qualitative and quantitative disclosures, including discussion of reasonably possible changes that might occur in the recognized tax benefits over the next 12 months; a description of open tax years by major jurisdictions; and a roll-forward of all unrecognized tax benefits, presented as a reconciliation of the beginning and ending balances of the unrecognized tax benefits on a worldwide aggregated basis. The Interpretation is effective as of the beginning of fiscal years that start after December 15, 2006. The Company is currently evaluating the effect that the adoption of FIN 48 will have on its financial position and results of operations.

In June 2006, EITF No. 06-3, How Sales Taxes Collected from Customers and Remitted to Governmental Authorities Should Be Presented in the Income Statement (That Is, Gross Versus Net Presentation) ("EITF No. 06-03"), was issued, which states that a company must disclose its accounting policy (i.e., gross or net presentations) regarding presentations of taxes within the scope of EITF No. 06-3. If taxes included in gross revenue are significant, a company must disclose the amount of these taxes for each period for which an income statement is presented. The disclosures are required for annual and interim financial statements for each period for which an income statement is presented. EITF No. 06-3 will be effective for the Company beginning April 1, 2007. Based on the Company's current evaluation of EITF No. 06-3, the Company does not expect its adoption to have a material impact on the Company's consolidated results of operations or financial position.

NOTE 2—NET INCOME (LOSS) PER COMMON SHARE AND PRO FORMA NET INCOME (LOSS) PER SHARE

The Company applies the provisions of EITF Issue No. 03-6, Participating Securities and the Two—Class Method under FASB Statement 128 ("EITF No. 03-6"), which established standards regarding the

computation of earnings per share by companies with participating securities or multiple classes of common stock. The Company's Series A through E redeemable convertible preferred stock are participating securities due to their participation rights related to cash dividends declared by the Company as described in Note 8.

Basic net income (loss) available to common stockholders per share is computed by dividing the net income (loss) available to common stockholders by the weighted-average common shares outstanding for the period. The net income (loss) available to common stockholders is calculated by deducting dividends allocable to the Company's redeemable convertible preferred stock from net income (loss) to determine the net income (loss) available to common stockholders.

Diluted net income (loss) available to common stockholders per share is computed giving effect to all potentially dilutive common stock, including options and common stock subject to repurchase using the treasury stock method, and all convertible securities using the if-converted method to the extent it is dilutive.

The following table sets forth the computation of basic and diluted net income (loss) attributable to common stockholders per share (in thousands, except per share data):

NOTE 6—BORROWINGS

At March 31, 2006, the Company had a line of credit with Mega International Commercial Bank Co., Ltd., which expired on May 9, 2006. The line of credit has subsequently been renewed until May 9, 2007. The line of credit provides for borrowings of up to $4,000,000 which are collateralized by a certificate of deposit of $1,000,000, certain accounts receivable balances and finished goods inventory. Borrowing is limited to $1,000,000 plus 70% of eligible United States accounts receivable balances and 35% of finished goods inventory with a sublimit of $500,000 for inventory. The terms of the line of credit include various covenants, the more restrictive of which requires the Company to maintain a working capital ratio of not less than 1.5 to 1, a tangible net worth, including redeemable convertible preferred stock, of not less than $15,000,000 and a debt to net worth ratio of less than 2 to 1. The Company's agreement with Mega International Commercial Bank Co., Ltd. contains a negative covenant, which precludes the Company from declaring dividends, other than dividends payable in stock, without the prior written consent of Mega International Commercial Bank Co., Ltd. The Company has been in compliance with these covenants during the fiscal year ended March 31, 2006 and for the nine month period ended December 31, 2006 (unaudited).

The first $1,000,000 of borrowings bear interest at the bank's reference rate (8.25% at December 31, 2006) (unaudited). Borrowings in excess of $1,000,000 bear interest at the bank's reference rate plus 1.00%. No amounts were outstanding under the line of credit at March 31, 2005 or 2006 and December 31, 2006 (unaudited).

NOTE 7—COMMITMENTS AND CONTINGENCIES

Operating leases

The Company leases office space and equipment under noncancelable operating leases with various expiration dates through May 2010. Rent expense for the years ended March 31, 2004, 2005 and 2006 was $568,000, $481,000 and $537,000, respectively. Rent expense for the nine month periods ended December 31, 2005 and 2006 was $407,000 (unaudited) and $395,000 (unaudited), respectively. The terms of the facility lease provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.

Future minimum lease payments under noncancelable operating leases with remaining lease terms in excess of one year at March 31, 2006 are as follows (in thousands):

Royalty obligation

The Company has license agreements to pay royalties on sale of products using the licensed technology through fiscal year 2007. Royalty expense for the years ended March 31, 2004, 2005 and 2006 was $154,000, $147,000 and $141,000, respectively. Royalty expense for the nine month periods ended December 31, 2005 and 2006 was $132,000 (unaudited) and $111,000 (unaudited), respectively.

Indemnification obligations

The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in the context of contracts entered into by the Company, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants related to such matters as title to assets sold and certain intellectual property rights. In each of these circumstances, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claims. Further, the Company's obligations under these agreements may be limited in terms of time and/or amount, and in some instances, the Company may have recourse against third parties for certain payments made by it under these agreements.

It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of the Company's obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements did not have a material effect on its business, financial condition, cash flows or

F-20

results of operations. The Company believes that if it were to incur a loss in any of these matters, such loss should not have a material effect on its business, financial condition, cash flows or results of operations.

Product warranties

The Company warrants its products to be free of defects generally for a period of three years. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in cost of revenues. Warranty costs were not significant for the years ended March 31, 2004, 2005 and 2006 or for the nine month period ended December 31, 2006 (unaudited).

Legal Proceedings

From time to time, the Company may be involved in litigation relating to claims arising out of day-to-day operations. As of December 31, 2006 (unaudited), the Company was not engaged in any legal proceedings that were expected, individually or in the aggregate, to have a material adverse effect on its business, financial condition, results of operations, or cash flows. See Note 13 for a description of certain pending litigation.

NOTE 8—REDEEMABLE CONVERTIBLE PREFERRED STOCK

Redeemable convertible preferred stock at March 31, 2005 and 2006 and September 30, 2006 (unaudited) consisted of the following (in thousands, except share data):

	Shares Issued and Outstanding	Liquidation Amount

Series D	3,136,668		4,705
Series E	120,000		456

	15,120,168	$	9,007

The holders of redeemable convertible preferred stock have various rights and preferences as follows:

Voting

The holders of any series of redeemable convertible preferred stock will have the same voting rights as a holder of the common stock.

In every vote for the election of directors, each holder of shares of redeemable convertible preferred stock shall be entitled to the number of votes equal to the number of whole shares of common stock into which such shares of redeemable convertible preferred stock could be converted pursuant to conversion at the record date for the determination of the stockholders entitled to vote in the election or, if no such record date is established, the date such vote is taken or any written consent of stockholders is solicited.

F-21

Dividends

Holders of Series A, B, C, D and E redeemable convertible preferred stock are entitled to receive noncumulative dividends at the per annum rate of $0.02, $0.0375, $0.10, $0.15 and $0.38 per share, respectively, when and if declared by the Board of Directors, prior to and in preference of any distribution to common stockholders. No dividends on redeemable convertible preferred stock or common stock have been declared by the Board of Directors from inception through September 30, 2006 (unaudited).

Liquidation

In the event of a liquidation, dissolution or winding up of the Company, including a merger or consolidation in which its stockholders do not retain a majority of the voting power in the surviving corporation, or a sale of substantially all assets, the assets of the Company legally available for distribution shall be distributed to the holders of Series A, B, C, D and E redeemable convertible preferred stock in an amount per share equal to $0.20, $0.375, $1.00, $1.50 and $3.80, respectively, plus all declared but unpaid dividends of such shares. Then, prior and in preference to any further distribution to the holders of redeemable convertible preferred stock, each holder of common stock shall be entitled to receive a maximum of $0.02 per share for each share of common stock then held. Any remaining available assets shall be distributed among the holders of the common stock and the redeemable convertible preferred stock in proportion to the shares of common stock held by them and the shares of common stock, which they then have the right to acquire upon conversion of shares of redeemable convertible preferred stock then held by them.

Should the Company's legally available assets be insufficient to satisfy the liquidation preferences, the funds will be distributed among the then outstanding holders of Series A, B, C, D and E redeemable convertible preferred stock, on an equal priority and pari passu basis according to their liquidation preferences.

Conversion

Each share of Series A, B, C, D and E redeemable convertible preferred stock shall be convertible, at the option of the holder, according to a conversion ratio of 1 to 1, subject to adjustment for dilution, into the Company's common stock. Each share of Series A, B, C, D and E redeemable convertible preferred stock automatically converts into fully paid nonassessable shares of common stock into which such shares are convertible at the then effective conversion ratio upon the closing of a firm commitment underwritten public offering pursuant to an effective registration statement filed under the Securities Act of 1933 covering the offer and sale of common stock for the account of the Company, other than a registration relating solely to a transaction under Rule 145 under the Act or to an employee benefit plan of the Company, in which the aggregate public offering price (before deduction of underwriters discounts and commission) equals or exceeds $10,000,000.

NOTE 9—COMMON STOCK

The Company's Certificate of Incorporation, as amended, authorizes the Company to issue 150,000,000 shares of $0.001 par value common stock.

F-22

NOTE 10—STOCK OPTION PLANS

In 1997, the Company adopted the 1997 Stock Plan (the "1997 Plan"). The 1997 Plan provides for the granting of stock options and stock purchase rights to employees and consultants of the Company. Options granted under the 1997 Plan may be either incentive stock options ("ISOs") or nonstatutory stock options ("NSOs"). ISOs may be granted only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees and consultants. The Company has reserved 8,450,000 shares of common stock for issuance under the 1997 Plan.

In February 2001, the Company adopted the 2000 Stock Option Plan (the "2000 Plan"). The plan provides for the granting of stock options and stock purchase rights to employees, consultants and directors of the Company. Options granted under the 2000 Plan may be either ISOs or NSOs. As of December 31, 2006, the Company had reserved 3,500,000 shares of common stock for issuance under the 2000 Plan.

In February 2001, the Company elected to terminate the 1997 Plan. The termination of the 1997 Plan included the provisions that no further options shall be granted under the 1997 Plan. However, the outstanding options and the shares issued upon exercise of the options granted under the 1997 Plan shall continue to be governed by the terms and conditions of the 1997 Plan. All 2,748,298 shares not granted as of the adoption of the 2000 Plan were cancelled.

Options under both the 1997 and 2000 Plans may be granted for periods of up to ten years, however in the case of ISOs granted to an optionee who, at the time the option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company, the term of the option shall be 5 years from the date of grant. The exercise price of an ISO and NSO shall not be less than 100% and 85% of the estimated fair value of the shares as determined by the Board of Directors on the date of grant, respectively, however the exercise price of an ISO and NSO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant, respectively. To date, the initial options granted to each person generally vest 25% on the first anniversary and subsequent anniversaries of the date of grant.

Stock purchase rights under the 1997 and 2000 Plans may be granted to employees and consultants and gives the grantee the right to purchase common stock at a certain price within a limited period of time. On exercise of a stock purchase right, the Company receives a right to repurchase the Common Stock at the original purchase price, which expires over a vesting period of usually four years.

On April 7, 2004, the Company's board of directors authorized the adoption of the 2004 Equity Incentive Plan (the "2004 Plan"). The maximum aggregate number of shares of stock that may be issued under the 2004 Plan is 3,500,000 as of December 31, 2006. This amount automatically increases on April 1, 2006 and each subsequent anniversary through 2014, by an amount equal to the lesser of (a) five percent (5%) of the number of shares of stock issued and outstanding on the immediately preceding March 31, or (b) 1,500,000 shares. The 2004 Plan provides for the grant of stock options, stock appreciation rights, performance awards and deferred compensation awards. Options granted under the 2004 Plan may be either ISOs, as defined under Section 422 of the Internal Revenue Code of 1986, or NSOs. There was no activity under the 2004 Plan in the year ended March 31, 2006 or in the nine month period ended December 31, 2006 (unaudited). In December 2006, the Company's Board of Directors terminated this plan.

On April 7, 2004, the Company's board of directors authorized the adoption of the 2004 Employee Stock Purchase Plan (the "Purchase Plan"). The maximum aggregate number of shares of stock that

F-23

may be issued under the Purchase Plan is 500,000. In addition, the Purchase Plan provides for an automatic annual increase in the number of shares available for issuance under the plan on April 1 of each year beginning in 2006 and continuing through 2014 equal to the smallest of (1) one percent of our then outstanding shares of common stock on the immediately preceding March 1, (2) 250,000 shares or (3) a number of shares as our Board may determine. The Purchase Plan is intended to qualify as an "employee stock purchase plan" under Section 423 of the Internal Revenue Code of 1986 with the purpose of providing employees with an opportunity to purchase the Company's common stock through accumulated payroll deductions. There was no activity under the Purchase Plan in the year ended March 31, 2006 or in the nine month period ended December 31, 2006 (unaudited). In December 2006, the Company's Board of Directors terminated this plan.

The Company calculated the fair value of each option grant in the periods presented using the Black-Scholes option pricing model and the following weighted average assumptions:

	Year Ended March 31,						Nine Months Ended December 31,
	2004		2005		2006		2005		2006
							(unaudited)
Risk-free interest rate	2.97	%	3.43	%	3.99	%	3.99	%	4.63-4.86%
Expected life (in years)	4.48		4.63		4.00		4.00		4.00
Volatility	80	%	75	%	73	%	73	%	69-71%
Dividend yield	0	%	0	%	0	%	0	%	0%

The weighted average fair value of options granted during the years ended March 31, 2004, 2005 and 2006 was $1.53, $2.69 and $2.57 respectively. The weighted average fair value of options granted during the nine month periods ended December 31, 2005 and 2006 was $2.57 (unaudited) and $3.08 (unaudited), respectively.

Had compensation cost for the Company's stock-based compensation plans been determined based on the fair value at the grant dates for the awards under a method prescribed by SFAS 123 and amended by SFAS 148 prior to the adoption of SFAS 123(R), the Company's pro forma net income (loss) would have been (in thousands, except per share amounts):

NOTE 12—EMPLOYEE BENEFIT PLAN

The Company provides a defined contribution retirement plan (the "Retirement Plan"), which qualifies under Section 408(k) of the Internal Revenue Code of 1996. The Retirement Plan covers essentially all United States employees. Eligible employees may make contributions to the Retirement Plan up to 15% of their annual compensation, but no greater than the annual IRS limitation for any plan year. The Retirement Plan does not provide for Company contributions.

NOTE 13—SUBSEQUENT EVENTS

On October 23, 2006, the Company was served with a civil antitrust complaint filed by Reclaim Center, Inc. and other plaintiffs in the United States District Court for the Northern District of California against the Company and a number of other semiconductor companies. The complaint was filed on behalf of a purported class of indirect purchasers of SRAM products throughout the United States. The complaint alleges that the defendants conspired to raise the price of SRAM in violation of Section 1 of the Sherman Act, the California Cartwright Act, and several other state antitrust, unfair competition and consumer protection statutes. Shortly thereafter, a number of similar complaints were filed by other plaintiffs in various jurisdictions on behalf of purported classes of both direct and

F-27

indirect purchasers. The Company has been served in some but not all of these subsequent actions. Many of these cases have been transferred by the Judicial Panel on Multidistrict Litigation to the Northern District of California. The Company believes that it has meritorious defenses to the allegations in the complaints, and the Company intends to defend these lawsuits vigorously. However, the litigation is in the preliminary stage and the Company cannot predict its outcome. The litigation process is inherently uncertain. Multidistrict antitrust litigation is particularly complex and can extend for a protracted time which can substantially increase the cost of such litigation. The defense of these lawsuits is also expected to divert the efforts and attention of some of the Company's key management and technical personnel. As a result, the Company's defense of this litigation, regardless of its eventual outcome, will likely be costly and time consuming. Should the outcome of the litigation be adverse to the Company, it could be required to pay significant monetary damages which could adversely affect the Company's business, financial condition, operating results and cash flows.

In December 2006, the Company's Board of Directors and stockholders approved an increase in the number of shares reserved for the issuance of stock options under the 2000 Plan by 500,000 shares. At the same time, the Board of Directors terminated the 2004 Equity Incentive Plan and the 2004 Employee Stock Purchase Plan.

In January 2007, the Company's Board of Directors approved the 2007 Equity Incentive Plan, with a reserve of 3,000,000 shares of common stock for issuance thereunder, and the 2007 Employee Stock Purchase Plan, with a reserve of 500,000 shares of common stock for issuance thereunder.
