MoSys Licenses Advanced 1T-SRAM Embedded Memory To Hudson Soft For Next Generation Product Designs

Gaming and entertainment leader chooses MoSys embedded memory technology for its performance, low power and increased density capabilities

SUNNYVALE AND SAPPORO, JAPAN (July 16, 2002) - MoSys, Inc. (NASDAQ: MOSY), the industry's leading provider of high density SoC embedded memory solutions, and Hudson Soft (NASDAQ Japan: 4822), a leading designer of home gaming and electronic entertainment products, today announced that Hudson Soft has licensed MoSys' advanced 1T-SRAMÒ embedded memory technology. Hudson Soft will use MoSys' 1T-SRAM technology to develop its next generation advanced products incorporating high performance, high density embedded memory blocks.

"Our engineering team evaluated MoSys' 1T-SRAM embedded memory technology and selected MoSys over other embedded memory technologies because of its superior performance, increased density and low power capabilities," said Satoshi Murakami, Corporate Officer of the Core Technology Division at Hudson Soft. "By using the MoSys 1T-SRAM embedded memory, we can offer advanced performance and more capabilities in our products than before at competitive prices."

"Hudson Soft is well known and respected as a leader and innovator in the home gaming and electronic entertainment products industry," noted Mark-Eric Jones, vice president and general manager of intellectual property at MoSys. "We are very pleased that Hudson Soft has chosen MoSys' 1T-SRAM technology and look forward to working with them as partners as they develop future products using our technology."

The detailed specifications and capabilities of MoSys' 1T-SRAM embedded memory blocks, and Hudson Soft's product incorporating the memory blocks will be announced at a later time.

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 .
