Vimicro Licenses MoSys' 1T-SRAM Embedded Memory

SUNNYVALE, Calif. & BEIJING--(BUSINESS WIRE)--Feb. 17, 2004-- MoSys, Inc. (Nasdaq:MOSY), the industry's leading provider of high density SoC embedded memory solutions and Vimicro Corporation, a cutting-edge digital multimedia chip company, today announced the licensing of MoSys' 1T-SRAM(R) embedded memory technology to be incorporated into Vimicro's next-generation multimedia (video/audio/graphics/music) processors for cellular phones.

"A significant consideration in cell phone design is the need for low power and enhanced multimedia processing capabilities and we believe that we can meet these new challenges by adopting MoSys' 1T-SRAM memory," said Jun Zhu, vice president of Engineering of Vimicro. "MoSys offers high-performance embedded memory technology utilizing less power and space, thus providing an enhanced product at a lower cost staying ahead of industry standards."

MoSys' 1T-SRAM technologies have already been silicon-proven in six process generations and are in high-volume production in many consumer and communications products.

"We are pleased to work with Vimicro to extend the use of our 1T-SRAM technology," said Mark-Eric Jones, vice president and general manager of intellectual property at MoSys. "By choosing our 1T-SRAM embedded memory, Vimicro will take advantage of the industry's highest quality embedded memory solution."

About MoSys

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' website at http://www.mosys.com.
