Rambus to Request NASDAQ Hearing Regarding Stock Listing; Receives expected notification for missing 10-Q filing date

Los Altos, California, United States -- August 16, 2006 -- Rambus Inc. (NASDAQ: RMBS) today announced that it plans to request a hearing before the NASDAQ Listing Qualifications Panel following the receipt of a NASDAQ Staff Determination notice stating that the Company is not in compliance with Nasdaq Marketplace Rule 4310(c)(14). This notice was received because the Company was not timely in filing its Quarterly Report on Form 10-Q for the period ended June 30, 2006. However, there can be no assurance that the hearing panel will grant the Company's request for continued listing. Pending a decision by the Panel, Rambus' common stock will remain listed on the NASDAQ Stock Market.

As previously announced, the Audit Committee of the Rambus Board of Directors is conducting an independent investigation to review the Company's historical stock option grant practices and related accounting. The Company had previously disclosed on July 19, 2006 that it would not be able to file its Form 10-Q on time while the investigation is ongoing. The Audit Committee is making every effort to complete its investigation, and the Company will make every effort to file its restated financial reports as soon as practicable after the completion of the investigation.
