Rambus Licenses Serial Link Technology to Intel for Ethernet Applications

LOS ALTOS, Calif., July 15, 2002 - Rambus Inc.(NASDAQ:RMBS), the world's leading developer of chip-to-chip interface technology, today announced that it has licensed its RaSer™ serial link technology to Intel for use in Ethernet network applications.

"Intel is committed to providing its customers with complete chip set solutions for our Ethernet portfolio," said Ted Odell, general manager of Intel's Networking Components Division. "We are taking advantage of Rambus' serial link technology to meet time-to-market requirements for our new products."

The Rambus RaSer 1-3.125 Gbps technology includes hard macro physical layer interface cells that can be integrated in ASIC or ASSP controller chips. RaSer cells have been licensed for many serial link applications including network equipment backplanes, InfiniBand™, Gigabit Ethernet and XAUI.

"The integration of the RaSer cell into an Ethernet silicon device reduces line card footprint and power versus the use of alternative discrete XAUI interface chips," said Kevin Donnelly, vice president of the Network Connections Division at Rambus Inc. "Our strength is in providing high-speed chip interconnect technology in ways that meet the industry's need for cost-effective, volume products."

RaSer Serial Link Technology

Rambus RaSer technology offers designers a scalable serial link architecture that addresses current and future serial link applications requiring the highest bandwidth. A complete serial link solution, the RaSer cell contains serializer, transmitter, receiver, deserializer, and clock recovery circuitry. The cell is designed to meet the physical layer requirements for a wide range of serial link applications, each of which may have different logical requirements (protocol, framing, coding, etc.). As a replacement to stand-alone discrete serial link components, the RaSer cell may be integrated with other communications functions in order to offer higher value network services and reduced component count.
