Derivative Suit Against Rambus Dismissed

LOS ALTOS, CA, July 10, 2003 -- Rambus Inc. (Nasdaq:RMBS), a leading provider of chip-to-chip interface products and services, today announced that the Court of Chancery of the State of Delaware has issued a stipulated order dismissing without prejudice the amended complaint in a consolidated derivative case against Rambus.

The dismissed derivative case arose from allegations concerning Rambus' 1991 - 1995 attendance at a standard setting body called JEDEC. The plaintiffs in this case agreed to stipulate to dismissal without prejudice following rulings favoring Rambus from the Court of Appeals for the Federal Circuit.

"Dismissal of this derivative case follows the path set by the Federal Circuit in its January ruling and in its en banc ruling in April," said John Danforth, vice president and general counsel for Rambus. "As with the recent dismissal of the shareholder class action against Rambus, we view this deference to the reasoning of the Federal Circuit as a further positive step."
