ABOUT MOSYS

Founded in 1991, MoSys develops, licenses and markets innovative
memory technology for semiconductors. The single transistor bit cell
used in 1T-SRAM technology 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
technology also offers the familiar, refresh-free interface and high
performance for random address access cycles associated with
traditional SRAMs. In addition, this technology can reduce operating
power consumption by a factor of four compared with traditional SRAM
technology, contributing to making it an ideal technology for
embedding large memories in System on Chip (SoC) designs. 1T-SRAM
technology is in volume production both in SoC products at MoSys’
licensees as well as in MoSys’ standalone memories. MoSys is
headquartered at 1020 Stewart Drive, Sunnyvale, California 94085. More
