(Nasdaq:MOSY), the industry's leading provider of high-density system-on-chip (SoC) embedded memory intellectual property (IP), today announced that Jim Pekarsky, Chief Financial Officer, will be presenting at the Thomas Weisel Partners Tech2007 Conference at the Fairmont Hotel in San Francisco on Wednesday, February 7, 2007 at 3:50 p.m. PST in the Pavilion Room.

About MoSys, Inc.

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 them ideal for embedding large memories in System on Chip (SoC) designs. MoSys' licensees have shipped more than 100 million chips incorporating 1T-SRAM embedded memory technologies, demonstrating excellent manufacturability in a wide range of silicon processes and applications. MoSys is headquartered at 755 N. Mathilda Avenue, Sunnyvale, California 94085. More information is available on MoSys' website at http://www.mosys.com.
