NEWS RELEASE

RAMBUS FILES FISCAL 2006 FINANCIAL STATEMENTS

LOS ALTOS, Calif. – September 14, 2007 – Rambus Inc. (Nasdaq:RMBS) today announced that it has filed with the Securities and Exchange Commission (SEC) its quarterly reports on Form 10-Q for the quarters ended June 30, 2006 and September 30, 2006, and its annual report on Form 10-K for the year ended December 31, 2006. The Company expects to file its quarterly reports on Form 10-Q for the quarters ended March 31, 2007 and June 30, 2007 as soon as practicable. Once it files the 2007 quarterly reports, the Company expects that it will be current in its SEC filings and expects to regain compliance with NASDAQ’s continued listing requirements.

“The completion of these filings is an important step forward,” said Harold Hughes, president and chief executive officer at Rambus. “We are committed to the best governance practices and providing the markets with full transparency of our accounting practices and controls.”

As previously announced, the Company’s filings were delayed as a result of the independent investigation relating to the Company’s historical stock option granting practices and related accounting. Upon completion of that investigation, the Company recorded a $169.4 million non-cash, pre-tax charge from 1997 through 2005.

As reported in the annual report on Form 10-K, the Company’s net loss for 2006 totaled $13.8 million. Loss before income taxes for this period was $25.7 million, which included $40.5 million of stock based compensation, $13.4 million in expenses related to the stock option investigation and $18.0 million of accruals for the proposed settlement of the class action suit related to the Company’s historical stock option granting practices.
