MOSAID Licenses QDR® II Memory Controller IP to Lead Customer

Design Licensing Group Provides High Speed Interface Solution

OTTAWA, Ontario, Canada – May 3, 2004 – MOSAID Technologies Incorporated (TSX:MSD) today announced the signing of a lead customer for a 333 MHz QDR® II SRAM memory controller IP block targeted at TSMC's 130nm process geometry.

The lead customer has signed a multi-use license for a complete memory controller solution, including the MOSAID QDR II® SRAM Controller, HSTL (High Speed Transceiver Logic) I/O library and DLL (Delay Locked Loop). The packaged MOSAID controller IP block employs hard macrocells to manage critical timing at the boundary of the physical interface. This enables high speed data rates of 666 Mbps, which are not achievable through traditional fully synthesizable implementations.

"This agreement further demonstrates the traction that our design licensing program is achieving," said George Cwynar, President and Chief Executive Officer of MOSAID. "Our customer is a global leader in providing advanced ASIC technology and we are pleased they have chosen our memory controller."

This complete memory controller solution is part of MOSAID's portfolio of IP products available for license through the Company's design licensing program. MOSAID offers specialized IP blocks and custom chip solutions to the marketplace, capitalizing on its expertise and reputation for excellence in the development of DRAM and other memory intensive products.
