MoSys and BiTMICRO Networks Sign Agreement for High-Performance 1T-SRAM(R) Memory Macro Geared for Family of Portable E-Disk Storage Solutions

E-Disk Leader Leverages 1T-SRAM(R) for Higher Performance and Lower Latency

SUNNYVALE, Calif. and FREMONT, Calif. -- April 19, 2007 -- MoSys, Inc. (Nasdaq: MOSY - News), the leading provider of high-density system-on-chip (SoC) embedded memory intellectual property (IP) solutions and BiTMICRO Networks, the leading provider of high-performance non-volatile solid-state disk and semiconductor solutions, announced today that BiTMICRO has become the latest licensee of MoSys' 1T-SRAM® embedded memory macro technology. BiTMICRO will leverage MoSys' technology to add new performance, latency and area advantages to its range of E-Disk® solid-state storage solutions.

At a speed of 350 Mhz in a standard 90-nm CMOS logic process, the MoSys-enabled BiTMICRO memory macro reaches a performance level that is unmatched by other embedded memory technologies.

"BiTMICRO's solid-state disk drive and flash disk-drive solutions are ideal for harsh, demanding, and mission-critical applications in the industrial, embedded, computer, communication, medical, military, and aerospace industries," said Rey Bruce, president and CEO of BiTMICRO Networks. "MoSys' 1T-SRAM technology was the only available solution that could meet the high performance, low latency and demanding reliability requirements of our system design."

"MoSys and BiTMICRO are collaborating closely to provide this performance-optimized design on a standard 90-nm CMOS process," said Chet Silvestri, president and CEO of MoSys. "The broad range of applications for the E-Disk solution further extends the reach of MoSys' 1T-SRAM technology into areas with demanding portability, durability, and speed requirements."
