<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Founded in 1991, MoSys develops, licenses and markets innovative memory
technologies for semiconductors. MoSys&#146; 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.&nbsp;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&#146; licensees have shipped more than 90 million chips incorporating
1T-SRAM embedded memory technologies, demonstrating excellent manufacturability
in a wide range of silicon processes and applications. MoSys is
headquartered at 755 North Mathilda, Sunnyvale, California 94085. More
information is available on MoSys&#146; website at http://www.mosys.com.</font></p>
