Rambus Continues Intel-Based System Verification

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Sept. 27, 1999--Rambus Inc. (NASDAQ:RMBS - news) stated today that
they are continuing to work with Intel and PC OEMs on system verification testing of RDRAM©-based platforms. The statements were made in response to
published speculation about the system verification testing underway for performance desktop PC platforms using the Intel 820 Chipset.

Some issues with platforms supporting three RIMM(TM) module connectors have been identified, and Intel, Rambus and the OEMs are working to quickly resolve
them. While the three-connector implementations offer OEMs maximum configuration flexibility, they result in over 1000 permutations of connectors, module
designs, frequency grades, optional parity/ECC for system test. The testing has shown that some configurations have issues relating to the combination of the memory
system components, module configurations, and motherboard design.

``Intel is committed to working with Rambus, the Direct RDRAM(TM) suppliers and its customers to validate the Intel 820 Chipset, and the systems that use it, as
soon as possible,' said Pete MacWilliams, Intel Fellow. ``Intel believes RDRAM is the memory solution that will provide the best performance with today's
high-performance microprocessors.'

``Dell is committed to working with Intel and Rambus to complete the platform validation of RDRAM-based systems,' said Carl Everett, senior vice president of
Dell Computer Corporation. ``Direct RDRAM is a strategic technology to Dell.'

``Toshiba's commitment to the Rambus©-memory architecture has not changed,' said Stephen Marlow, vice president of Toshiba America Electronic Components'
Memory Business Unit. ``We firmly believe that RDRAM provides the optimum solution for high performance PC and Consumer platforms,' he added.

``When the RDRAM-based platforms are released they will have passed substantial, broad, and rigorous system-level testing. The goal of Rambus and our partners
is to provide a solution at a higher quality standard than what occurred at prior memory transitions,' said Dave Mooring, senior vice president of Rambus Inc.

Rambus Inc. (NASDAQ: RMBS - news), based in Mountain View, Calif., develops and licenses high-speed chip-to-chip interface technology that enables
semiconductor memory devices to keep pace with faster generations of processors and controllers. Providers of Rambus-based integrated circuits include the
world's leading DRAM, ASIC and PC controller manufacturers. Currently, eight of the world's top-10 semiconductor companies license Rambus technology. More
information on Rambus Inc. and its high-bandwidth interface technology is available at rambus.com.

Hi John Walliker; Re that Vref on Rambus (and DDR, as well). While it is supposed to be a DC signal, no such thing ever exists in actual systems. Noise is everywhere. Not that this means that this is the cause for the problem. It's just that they never publish specs which give what the impedance or capacitance of the input pin is. In other words, the specs are written as if the pins really were at a perfect DC level, as if this were ever achievable.
