MoSys Licenses 1T-SRAM for Advanced 55NM Process Technology to NEC Electronics

Technology to Help Drive New Advances in IC Products for Innovative Consumer, Networking, Graphics Applications

SUNNYVALE, CA -- May 23, 2007 -- MoSys, Inc., the industry's leading provider of high-density system-on-chip (SoC) embedded memory intellectual property (IP), today announced that NEC Electronics (TSE: 6723) has licensed MoSys' 1T-SRAM technology for use in the semiconductor manufacturer's cutting-edge 55-nm process. The combination of Mosys' 1T-SRAM and NEC Electronics' 55-nm embedded DRAM process technology can produce integrated circuit (IC) devices with the low cost and low power consumption characteristics needed to enable next-generation consumer products. The high-speed attributes of the MoSys 1T-SRAM also enables the technology to address high-performance networking and graphics applications.

"The move to 55-nm is further evidence of the rapid scalability of our 1T-SRAM technology. We have been able to continuously scale this technology from 250nm to the current 55nm node. We will continue to rapidly scale to 45nm and beyond," said Chet Silvestri, president and CEO of MoSys. "This scalability ensures our customers will have access to our high density memory technology in the industry's most advanced process technologies. Extending our partnership with NEC Electronics to include 55nm is an important milestone in delivering on this promise."
