Virtual Silicon to Offer IP for UMC's ASIC Foundry Process

SUNNYVALE, Calif. --June 23, 2003 - Virtual Silicon Technology Inc., a leader in semiconductor intellectual property (SIP), today announced that it has expanded its portfolio of SIP components that target UMC's (NYSE: UMC) 0.15 micron ASIC foundry process; thereby enabling UMC foundry customers to license a wider range of Virtual Silicon's IP components for their 0.15-micron silicon designs. Virtual Silicon has been offering SIP components for UMC's L150 process since 2000.

"Virtual Silicon has a long track record of success in delivering IP for our 0.25, 0.18, and 0.13 micron processes. We welcome their latest SIP components which target our L150 ASIC process to satisfy our customers' more sophisticated 0.15 micron ASIC design requirements," said Ken Liou, director of UMC's Design Support division. "Our foundry customers now have access to additional IP that helps to lower development costs and provide faster time to silicon with lower risk."

"Offering a more robust portfolio of IP on UMC's L150 ASIC foundry process is a natural continuation of a long and successful relationship between UMC and Virtual Silicon," said John A. Ford, vice president of marketing for Virtual Silicon. "We look forward to the opportunity to extend our continuing relationship with UMC in supporting our mutual customers' IP needs."

Virtual Silicon's product offering for UMC's L150 ASIC process includes standard cells, staggered and in-line basic I/Os, a PLL compiler, a high density single port SRAM compiler, a dual port SRAM compiler, a two-port memory compiler and a diffusion ROM compiler. The IP is slated to be verified on a series of test chips to be run at UMC by Q2, 2004.
