Rambus and Zuken Jointly Develop PCB Design System for Direct RDRAM

2000--Rambus Inc. (Nasdaq:<A HREF="aol://4785:RMBS">RMBS</A>), the leading
provider of high bandwidth chip connection technology, and Zuken Inc.
(Yokohama, Japan), one of the world's leading providers of professional
software solutions for the design of PCB/MCM/IC packages and systems, today
announced that they have jointly developed a CAD software package for Direct
RDRAM(tm)-based system PCB layout on the CR-5000 platform.

The new software package enables expeditious state-of-the-art layout by PCB
designers with minimal transmission line theory know-how. The Rambus(r)
software package is suitable for various applications including PC and
workstations, networking and digital consumer products.

The new Rambus software package includes reference schematics, reference
layout, tools to calculate several important design parameters and tools for
impedance and trace length matching. Users of the Rambus software package can
optimize PCB layout with the best electrical characteristics developed by
Rambus with the versatile and revolutionary functionality provided by Zuken's
CR-5000 platform.

"The strategic alliance between Zuken and Rambus for many years enabled Zuken
to develop a revolutionary PCB design solution," said Jinya Katsube, COO of
Zuken Inc. "Zuken believes that Rambus technology will continue to be
extensively used for various applications such as PC, workstation, networking
equipment and digital consumer products. With the combination of Rambus'
high-level technology, our know-how and consulting relationships with our
large customer base, we are convinced of our success. Zuken expects its
business related to Rambus technology, including sales of the software
package announced today, and services from consulting to generate revenue of
about $10M in 2003."

In the future, Zuken will offer PCB design solutions to support next
generation high-speed digital circuits as it expands sales worldwide. New
tools developed to improve the precision of trace length matching and
impedance control using thin traces will also be included. Rambus will
provide Zuken with updated reference layouts which Zuken will incorporate
into the Rambus software package.
