Rambus and Denali to Provide Complete DDR Memory Controller Design Solutions

Enables integration of physical and logic layers, reducing risk and improving time to market for memory system makers

DENALI MEMCON BOSTON, WESTFORD, Mass. – May 13, 2004 -- Rambus Inc. (Nasdaq:RMBS), a leading developer of chip interface products and services, and Denali Software, a leading provider of semiconductor intellectual property (IP) and electronic design automation (EDA) tools for chip interface design and verification, today announced plans to jointly provide DDR memory controller design solutions. Combining Rambus drop-in DDR interface cells with Denali’s Databahn DDR controller IP provides chip designers with an integrated design environment that will reduce risk and improve time to market when developing and verifying DDR memory controller interfaces.

"Increasing memory speeds and new memory architectures are only two of the critical issues engineers have to worry about when designing a memory system," said Rich Warmke, director of marketing of the Memory Interface Division at Rambus. "Denali has generated significant momentum in the DDR controller space and partnering with them allows us to provide our customers with proven, configurable solutions that make it easier for engineers to develop high-performance memory systems."

Denali memory controllers and Rambus DDR1/DDR2 interface cells easily integrate together into complete memory solutions on customers’ designs. Rambus is providing a new family of DDR memory controller interfaces, including mainstream DDR1 and DDR2 up to 800MHz data rates and graphics DDR, including GDDR1, GDDR2, and GDDR3 up to 1600MHz data rates. Rambus DDR memory controller interface cells are full-featured drop-in physical layer (PHY) cells. The interface cells use proven technology that allow customers to dramatically improve time to market, minimize design risk and avoid potential re-spin costs. Rambus also offers system engineering services to further accelerate time to market, and ensure the interface operates at high frequency in the system environment. The solution is additionally supported with Denali’s verification IP products for simulating and verifying the memory system before implementation in silicon.

"We’re pleased to be able to help our customers reduce risk and overall development time through our alliance with Rambus," said Mike McKeon, director of strategic products at Denali. "Denali’s silicon-proven Databahn controllers, combined with Rambus’s interface cells, is ideal for customers who need maximum speed and reliability, and minimum design risk for their memory interfaces."

Details of the joint DDR memory system solution will be presented at the MemCon event starting today in Westford, Massachusetts. The full-day event is focused on DDR2 systems and technology, and features exclusive presentations from Denali, Rambus, and 9 other memory companies. Registration is free to industry professionals online at: www.memcon.com.
