Samsung Licenses Rambus Yellowstone Interface Solution

World's largest DRAM manufacturer to incorporate advanced interface into next-generation DRAMs

LOS ALTOS, California, United States  - 06/30/2003   Rambus Inc. (Nasdaq:RMBS), a leading developer of chip-to-chip interface products and services, today announced that Samsung, the world leader in advanced memory technology, has signed a licensing agreement to incorporate Rambus' Yellowstone technology into its next-generation DRAM products for use in low-cost, high-speed applications.

"Samsung and Rambus have enjoyed a great partnership for a long time - adopting the Yellowstone interface into our product portfolio ensures we are providing our customers with a reliable and high quality interface," said Soo In Cho, executive vice president of Samsung Electronics' memory division. "Samsung believes Yellowstone-enhanced DRAMs are an ideal solution for high-performance, low-cost consumer, graphics and networking applications."

Yellowstone offers a quantum leap in performance in memory signaling while lowering system cost through pin-count reduction and support for low-cost, high-volume PCBs and packages. The flexible architecture enables customers to meet challenging power and cost targets. Yellowstone is expected to achieve data rates of 3.2 to 6.4 GHz and beyond, enabling up to 100 GB/sec of memory system bandwidth.

"Samsung continues to be a very strong and valuable partner for Rambus," said Dave Mooring, president of Rambus. "Having Samsung as a Yellowstone DRAM partner ensures adequate supply to the industry of high-speed products for the next generation high-volume applications."

The Yellowstone architecture brings flexibility, simplicity and savings in memory system design through a number of innovations. FlexPhase™ circuit technology is one of these innovations - it enables precise, on-chip alignment of data and clock, minimizing the need for PCB trace length matching and strict PCB timing constraints, resulting in a significant breakthrough for memory systems. The Yellowstone architecture also enables pin-count reduction and elimination of external termination resistors, further lowering overall system cost.

This release contains forward-looking statements that are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements about ensuring adequate supply to the industry of high-speed products for the next generation high-volume applications. Such forward-looking statements are based on current expectations, estimates and projections about the Company's industry, management's beliefs, and certain assumptions made by the Company's management. Among the reasons which could cause actual results to differ materially are the possibility of inadequate shipments of Rambus Yellowstone memory devices, the market response to these products, the continued deterioration in the DRAM market, any delay in the development of Rambus-based products by licensees, any delay in the development and shipment of new Rambus products, any delay in the development and shipment of products compatible with Rambus products, a strong response of the market to competing technology, a lack of progress on price and cost reduction by suppliers, a failure to sign new contracts or maintain existing contracts, adverse litigation decisions and other factors that are described in our SEC filings including our 10-K and 10-Qs.
