MoSys' 1T-SRAM Memory Silicon-Verified on DongbuAnam's 0.18-Micron Standard Logic Process; 0.13-Micron Verifications Initiated

SUNNYVALE, Calif. & SEOUL, Korea--(BUSINESS WIRE)--Sept. 7, 2004 -- MoSys, Inc. (Nasdaq:MOSY) the industry's leading provider of high density SoC embedded memory solutions and DongbuAnam semiconductor (DongbuAnam), have announced the silicon verification of MoSys' 1T-SRAM(R) memory technology on DongbuAnam's 0.18-micron standard logic process, and initiated 0.13-micron verification as well. With these manufacturing milestones completed, DongbuAnam's customers can confidently select MoSys' 1T-SRAM technology to meet the memory requirements of their System-on-Chip (SoC) designs.

"DongbuAnam's silicon verification of MoSys' 1T-SRAM memory gives our customers access to an embedded memory technology that passes the test of successful manufacturing. This reduces design risk and enhances the ability to create complex SoC designs," stated Jae Song, vice president of Marketing at DongbuAnam. "Our cooperation with MoSys provides our customers with a seamless path from design to manufacturing, and enables creation of system-level devices using MoSys' unique, high density memory architecture."

"MoSys' 1T-SRAM embedded memory technology lets DongbuAnam's customers achieve system-level integration with increased memory density and logic on the same chip," commented Dr. Fu-Chieh Hsu, President and CEO of MoSys Inc. "We look forward to working with DongbuAnam, its customers and partners."

About MoSys and 1T-SRAM

Founded in 1991, MoSys (Nasdaq:MOSY), develops, licenses and markets innovative memory technologies for semiconductors. MoSys' patented 1T-SRAM technologies offer a combination of high density, low power consumption, high speed and low cost unmatched by other available memory technologies. The single transistor bit cell used in 1T-SRAM memory results in the technology achieving much higher density than traditional four or six transistor SRAMs, while using the same standard logic manufacturing processes.

1T-SRAM technologies also offer the familiar, refresh-free interface and high performance for random address access cycles associated with traditional SRAMs. In addition, these technologies can reduce operating power consumption by a factor of four compared with traditional SRAM technology, contributing to making it ideal for embedding large memories in System on Chip (SoC) designs. MoSys' licensees have shipped more than 50 million chips incorporating 1T-SRAM embedded memory, demonstrating the excellent manufacturability of the technology in a wide range of silicon processes and applications. MoSys is headquartered at 1020 Stewart Drive, Sunnyvale, California 94085. More information is available on MoSys' Web site at http://www.mosys.com.
