Company to provide technology and design resources for evaluation effort of XDR™ memory architecture

Los Altos, California, United States  - 11/07/2007   Rambus Inc. (NASDAQ:RMBS), one of the world's premier technology licensing companies specializing in high-speed memory architectures, has signed a memorandum of understanding with Intel to explore possible uses for Rambus' family of XDR™ memory solutions.

Rambus plans to dedicate certain technology and design resources to the effort and the evaluation will be done on Intel’s silicon process technology. The Company stressed that Intel was only evaluating the technology for possible future uses and has no specific product plans for the XDR memory technology at this time.

The XDR memory architecture features key enabling technologies built on patented Rambus innovations that include low-voltage, low-power Differential Rambus Signaling Level (DRSL); FlexPhase™ circuit technology for precise on-chip alignment of data with clock; and Dynamic-Point-to-Point (DPP) for scalable point-to-point signaling on the data bus.
