DPA Attacks vs. unknown input: a 1st-order Attack on Counter Modes – CHES 2006

Los Altos, California, United States – 08/22/2006
Rambus Inc. (NASDAQ: RMBS) today announced that the United States District Court for the Northern District of California conditionally stayed the final stage of the Hynix vs. Rambus matter until February 2, 2007 or the issuance of a final order of the Federal Trade Commission (FTC), whichever occurs first.

The Court noted two reasons for the stay, (1) the potential for a resolution of this case once the FTC sets royalty rates on SDRAM and DDR SDRAM, and (2) to afford Hynix ninety days to try to establish the applicability of any findings of the FTC to this phase of the Hynix case.

The stay for the third phase of the trial has been conditioned in part upon Hynix’s agreement, within ten days, to post security. The security is intended to ensure payment of previously awarded damages together with damages for infringing sales between January 1, 2006 and February 2, 2007 (at royalty rates of 1% for SDRAM and 4.25% for DDR SDRAM and DDR2), together with prejudgment interest.

“The Court has expressed its view that the Commission’s decision has increased the potential for a resolution of this case and the several other litigations between Rambus and various DRAM manufacturers,” said Robert Kramer, acting general counsel at Rambus. “We are hopeful that such an industry-wide resolution can be achieved and we will continue to work toward that end. In the event this case proceeds to trial, we expect to demonstrate to the Court that the Commission’s findings should not be given prima facie weight.”

This case was originally filed by Hynix against Rambus in August 2000 seeking declaratory judgments that certain Rambus patents are invalid and not infringed. Earlier this year, all ten of ten patent claims presented to a jury in the case were found to be valid and infringed, and Rambus was awarded damages.

Receives expected notification for missing 10-Q filing date

Los Altos, California, United States – 08/16/2006
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.

Los Altos, California, United States – 08/15/2006
Rambus Inc. (NASDAQ: RMBS) announced today that Geoff Tate, former CEO of the Company from 1990 through 2005, has given notice of his intention to resign from its Board of Directors. “On behalf of Rambus, we thank Geoff for his efforts in building the Company’s strong technology base and for his many contributions to the Company as CEO and Director,” said Kevin Kennedy, Chairman of the Rambus Board of Directors.

As announced on July 19, 2006, the Audit Committee of the Rambus Board of Directors has reached a preliminary conclusion that the actual measurement dates for certain stock option grants issued in prior years differ from the recorded grant dates for such awards. During this period, Geoff was CEO and the sole member of the Stock Option Committee. Given these circumstances and to ensure that there is not even the appearance of a conflict of interest, Geoff felt he could best support the Company by resigning from his position on the Board as Rambus resolves these issues.
