MoSys Licenses 1T-SRAM Embedded Memory Technology To Motorola's Semiconductor Products Sector

SUNNYVALE, CALIFORNIA (May 15, 2002) - MoSys, Inc. (NASDAQ: MOSY) the industry's leading provider of high density SoC embedded memory solutions, today announced the licensing of MoSys' 1T-SRAMÒ embedded memory technology to the Semiconductor Products Sector (SPS) of Motorola, Inc. (NYSE: MOT). The 1T-SRAM embedded memory technology will be used to enable the incorporation of high performance, high density embedded memory blocks.

"We are very pleased that Motorola has chosen to license MoSys' 1T-SRAM technology," said Mark-Eric Jones, vice president and general manager of intellectual property at MoSys. "Our 1T-SRAM technology has been proven in volume production to offer cost savings, quality and reliability improvements that cannot be matched by other embedded memory technologies. As the proportion of SoC die area occupied by memory continues to grow these benefits translate to dramatic advantages for the whole SoC."

To date, 1T-SRAM embedded memory technology at MoSys licensees has passed 20 million units currently in production. These shipped devices represent a total of over one billion megabits (1,000,000,000,000,000 bits) of 1T-SRAM embedded memory now in use by licensees and their customers.

ABOUT MOSYS

Founded in 1991, MoSys (NASDAQ: MOSY), develops, licenses and markets innovative memory technology for semiconductors. MoSys' patented 1T-SRAM technology offers 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 technology 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 technology also offers the familiar, refresh-free interface and high performance for random address access cycles associated with traditional SRAMs. In addition, this technology can reduce operating power consumption by a factor of four compared with traditional SRAM technology, contributing to making it an ideal technology for embedding large memories in System on Chip (SoC) designs. 1T-SRAM technology is in volume production both in SoC products at MoSys' licensees as well as in MoSys' standalone memories. MoSys is headquartered at 1020 Stewart Drive, Sunnyvale, California 94085. More information is available on MoSys' website at www.mosys.com.
