Rambus Announces Fully Integrated, Optimized PCI Express Solution

Industry-Leading Integrated Controller and PHY Deliver Superior Results in Broad Range of Applications

LOS ALTOS, Calif. -- Aug. 8, 2005 -- Rambus Inc. (Nasdaq:RMBS), one of the world's premier technology licensing companies specializing in high-speed chip interfaces, today announced the availability of its fully integrated PCI Express(1) solution. This complete solution consists of silicon-proven digital controllers and PHY cells meeting the PCI Express 1.1 base specification. Supported by a PCI Express evaluation kit, the Rambus integrated solution is ideal for customers searching for end-to-end implementation and validation, which eliminates the interoperability risks and complexities associated with multi-vendor IP.

Rambus's PCI Express solution includes vertically integrated testing features to help customers facilitate system bring-up and debug for improved production test coverage. The Rambus solution allows design optimizations to be made across the PHY and logic layers to result in lower power, area and latency for cost- and performance-sensitive applications.

"Our complete solution with both the digital controller and PHY ensures our customers can get their products to market faster by reducing integration and validation risks as well as providing value-added features that go beyond the current specifications," said Laura Stark, vice president of the Platform Solutions Group at Rambus. "Designers are concerned about getting their PCI Express implementation to work the first time. With our solution they have a reliable, fully verified and interoperability-tested solution that greatly reduces the risk of integrating third-party IP."

For a streamlined design-in experience, Rambus offers developers the PCI Express evaluation kit, a system level evaluation platform that supports:

•  Electrical characterization;
•  Compliance and interoperability validation;
•  Performance evaluation and optimization;
•  Application and software development;
•  Thorough validation of the target application.

Rambus PCI Express digital controllers are highly configurable, and are delivered with a complete test environment, test cases and synthesis environment for maximum ease of integration. Rambus PCI Express PHY cells are available on multiple foundry and captive processes at process nodes ranging from 180nm to 65nm. Numerous Rambus customers are in production in high-volume applications such as graphics, chipsets, storage, and communications ICs.

Rambus has also demonstrated its Turbo PCI Express platform with serial links operating at 5.0Gbps and 6.25Gbps data rates to meet future PCI Express requirements. The Rambus PCI Express solution is represented with multiple entries on the PCI-SIG Integrators List, having passed compliance and interoperability testing by Rambus customers and partners.
