ABOUT MOSYS

Founded in 1991, MoSys, 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 65 million chips incorporating 1T-SRAM embedded memory
technologies, demonstrating excellent manufacturability in a wide range of
silicon processes and applications. MoSys is headquartered at 1020 Stewart
Drive, Sunnyvale, California 94085. More information is available on MoSys’
