Vitesse and Samsung Present First OC-48 Traffic Management Solution with 1066MHz RDRAM Memory attached at Networld+InterOp

Las Vegas, Nevada, United States  - 05/08/2001   Vitesse Semiconductor Corporation (Nasdaq: VTSS), Samsung Electronics and Rambus Inc. today announced the first system solution based on 1066MHz RDRAM® memory at the Networld+InterOp Conference in Las Vegas. On display in the Rambus booth (#8912) and the Vitesse Semiconductor booth (#8408), the Vitesse PaceMaker™ 2.4, a highly integrated traffic management engine for full rate OC-48 ATM and packet processing, incorporates two RDRAM interfaces and when coupled with 1066MHz RDRAM components from Samsung, achieves an impressive 12.5M packets per second throughput.

"High performance network processors require high-bandwidth memory. The scalability of RDRAM memory allows our customers to cost-effectively select the appropriate speed and density of memory for their applications," said Dr Raif Onvural, Vice President of the Multi Service Solutions Group at Vitesse Semiconductor Corporation. "Currently supporting both 800MHz and 1066Mhz RDRAM memory, the Pacemaker 2.4 is now available to customers and will process packets and cells at full duplex OC-48 data rate. The next version of the PaceMaker, currently in design, will also support both RDRAM speed configurations."

"Samsung Electronics has been at the forefront of RDRAM memory production and is committed to delivering the highest performance memory products to our leading-edge customers, such as Vitesse," said John Kang, Senior Vice President at Samsung Electronics. "We are confident and ready to support the 1066MHz RDRAM speed bin and expect that with our expertise in RDRAM production, yields will be very reasonable. Already, Samsung has components available in sample quantities."

As the next step in the evolutionary roadmap, the 1066MHz RDRAM is a simple bin split of the industry standard 800MHz RDRAM currently available from leading RDRAM manufacturers. The 1066MHz RDRAM delivers 2.1 GB/s of bandwidth from a single device, and is initially targeted for consumer, graphics and communications applications that will benefit from the increased performance, bandwidth and scalability using one to four devices mounted directly on the motherboard.

Samsung plans to support customer demand for 1066MHz RDRAMs in the third quarter of 2001. Yields of 1066MHz RDRAMs will continuously increase as Samsung moves to finer design rules for third generation RDRAMs. Two other RDRAM manufacturers, Elpida Memory Inc and Toshiba Semiconductor, have also announced plans to support 1066MHz RDRAM. All three manufacturers will support both the 800MHz and 1066MHz speed bins in 2001.
