UMC's 90nm URAM Used in Mobile TV Applications

Foundry’s Embedded Memory Solution Enhances Performance and Reduces Costs for DiBcom’s Products

HSINCHU, Taiwan -- December 10, 2007 -- UMC, a leading global semiconductor foundry, today announced that DiBcom, the world leading provider of Mobile TV solutions, has successfully adopted UMC’s URAM embedded memory solution for its 90nm products manufactured at the foundry. UMC’s URAM, a high-density embedded memory solution, enables higher performance, lower power consumption, and smaller chip area for DiBcom’s mobile TV chips, when compared with traditional SRAM memory implementations.

“At DiBcom we maintain our leadership by always looking for new ways to offer the best solutions and more value to our customers,” said David Dorval, vice president of Operations at DiBcom. “UMC’s URAM allows us to reduce power and cost, two important factors for the emerging Mobile TV market.”

S C Chien, vice president of advanced technology development at UMC, said, “UMC is constantly developing innovative technology solutions to enhance the performance capabilities of our customers’ products. The power and performance advantages offered by our URAM memory solution, which has an interface similar to that of SRAM, is poised to help DiBcom increase the competitiveness of their new generation mobile TV products.”

About UMC’s URAM

UMC’s URAM, part of the company’s IP memory family, is intended for a wide range of applications including communications, graphics and imaging systems, and storage devices. The memory bitcell is 1/4 to 1/5 the size of 6T SRAM and its macro area is approximately 1/2 to 1/3 times smaller than SRAM, which in turn allows for more efficient chip area utilization, flexibility and smaller chip size. The URAM cell is completely compatible with UMC’s logic process for seamless integration, with few additional process steps needed. URAM is shrinkable to 45nm and below and features low soft error rate and performance ranges of 200MHz for high speed macro, and 166MHz for low power macro designs.
