SUNNYVALE, Calif.—(BUSINESS WIRE)—October 30, 2008— MoSys, Inc., (NASDAQ: MOSY), a leading provider of high-density system-on-chip (SoC) memory and analog/mixed-signal intellectual property (IP), today reported financial results for its third quarter ended September 30, 2008.

Recent Highlights

• Reported total revenue of $4.1 million, a 27 percent increase over the previous quarter
• Completed the quarter with cash and investments of $72.1 million
• Authorized and commenced repurchases under a $5 million stock repurchase plan

Management Commentary

Commenting on the quarter’s results, Len Perham, MoSys’ President and Chief Executive Officer, stated, “During the third quarter, we recorded sequential increases in both license and royalty revenue. License revenue was driven in part by the delivery of three application specific system macro solutions to customers for our Dual-Port Display Driver IC (DDI) technology. We believe there is a significant opportunity for embedded 1T-SRAM technology in DDIs for the small-to-medium sized LCD market, where applications, such as advanced mobile handsets, require higher memory density, lower costs and reduced power consumption. Traction with our DDI customers is strong, and we expect this trend to continue.”

“Additionally, royalty revenue increased during the quarter, primarily due to further ramping with a major foundry partner at the 90nm process node. This foundry partner develops and markets memory macro solutions based on our patented embedded 1T-SRAM technology. We recently completed the verification of our 1T-SRAM technology at Level III and IV on TSMC’s 90nm general purpose eDRAM process. The achievement of this milestone further demonstrates the manufacturability, functionality and reliability of our proprietary IP at the 90nm process node and positions MoSys well for scaling to more advanced nodes in the near future.”

Mr. Perham concluded, “Looking forward, we remain focused on strategic product and technology development to address the design challenges of our customers and foundry partners. Additionally, we are executing on our sales initiatives to secure additional license agreements, but our near term visibility into the timing is limited. We are continuing to take the steps necessary to position the company for future growth in spite of the uncertain economic times we are dealing with at present.”
