U.S. District Court For Northern California Conditionally Stays Hynix Trial Against Rambus

Los Altos, California, United States -- August 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.
