environment during the first half of 2003, and many of our customers
have delayed the start of their development projects as well as the
deployment of completed projects into production which has certainly
impacted current revenues. Despite these difficulties, we continue to
effectively focus on the further expansion and proliferation of our

Dr. Hsu further stated, “With respect to the long anticipated
market improvement, we remain cautious in predicting the pace of any
significant recovery. Visibility remains difficult even for the

Founded in 1991, MoSys (NASDAQ: MOSY), 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
50 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’ website at
