SUNNYVALE, Calif., Oct. 28 /PRNewswire-FirstCall/ — MoSys, Inc.
(Nasdaq: MOSY), a leading provider of high-density system-on-chip (SoC) memory
and analog/mixed-signal intellectual property (IP), today announced it has
achieved Level III and IV verification of its 1T-SRAM embedded memory
technology on TSMC’s 90 nanometer (nm) General Purpose eDRAM process by the
foundry’s IP Alliance program.

TSMC’s IP Alliance includes a quality management program that requires IP
cores to demonstrate manufacturability and functionality. MoSys’ 1T-SRAM
memory macros have been tested and verified to Levels III and IV, including
full characterization of seven-corner split wafer lots and full high
temperature operating life (HTOL) testing on three distinct wafer lots.

“We are pleased to reach this important milestone in which MoSys’
patented technologies were successfully incorporated into SoC designs
fabricated using TSMC’s 90 nm advanced processes,” said Len Perham, President
and Chief Executive Officer of MoSys. “By leveraging the extensive testing
and stressing performed to reach TSMC Level III and IV compliance, MoSys can
now more clearly demonstrate the reliability of MoSys’ 1T-SRAM memories.”
