Securities to Remain Listed on Global Select Market

LOS ALTOS, Calif.-- July 13, 2007 --Rambus Inc. announced that it received a letter today from the Board of Directors of the Nasdaq Stock Market (the “Nasdaq Board”) informing the Company that the Nasdaq Board has called the May 25, 2007 decision of the Nasdaq Listing and Hearing Review Council (the “Listing Council”) for review. In its decision, the Listing Council had determined to suspend the Company’s securities from trading on July 20, 2007, if the Company did not file its delinquent quarterly and annual reports with the Securities and Exchange Commission by July 18, 2007. The Nasdaq Board has determined to stay the decision to suspend the Company’s securities from trading, pending further consideration from the Nasdaq Board. The Company’s securities will remain listed on the Nasdaq Global Select Market during the review by the Nasdaq Board.

Rambus intends to file its delinquent quarterly and annual reports as soon as practicable following the completion of its restatement. There can be no assurance that the Nasdaq Board review will be favorable to the Company.
