Federal Trade Commission Authorizes Rambus to Receive Withheld Royalties

Los Altos, California, United States  - October 17, 2008 --  Rambus Inc. (Nasdaq:RMBS), one of the world's premier technology licensing companies specializing in high-speed memory architectures, today announced it has received an order from the Federal Trade Commission (FTC) authorizing the receipt of Excess Consideration pursuant to any contingent contractual obligations.

"The Commission's order confirms that we are able to receive the royalty payments that were withheld as a result of the Commission's prior orders," said Tom Lavelle, senior vice president and general counsel for Rambus. "With the FTC's orders vacated, we are able to receive the royalties that we negotiate in good faith with our licensees or prospective licensees."

On April 22, 2008, the District of Columbia Court of Appeals overturned the FTC's orders and remanded the matter back to the FTC for further proceedings consistent with the Court's opinion. Further, on August 26, 2008, the CADC denied the FTC's request for en banc rehearing and issued its final mandate on September 9, 2008. Subsequently, the FTC issued an order acknowledging that Rambus may collect Excess Consideration currently being held in abeyance.

As of June 30, 2008, there was $5.2 million held in abeyance and excluded from revenue. Of this amount, Rambus will recognize $0.9 million of revenue in the quarter ended September 30, 2008 and the balance when it receives the payments from its customers.
