July 20, 2001, – Los Altos, CA -The District Court in Mannheim, Germany, today decided to appoint an independent technical expert to evaluate the infringement of Rambus’ patent by Infineon Technologies’ SDRAM and DDR SDRAM memory products.

The independent technical expert is to be appointed by September 15, 2001.

After the expert delivers an opinion, the Mannheim Court will determine whether the Infineon SDRAM and DDR SDRAM memory products infringe Rambus’ first European patent EP 525 068, as Rambus has claimed in its suit against Infineon.

“Rambus is pleased with the ruling by the District Court in Mannheim,” said Geoff Tate, CEO of Rambus. “The independent technical experts appointed by the court in Monza, Italy found Micron’s SDRAM infringed Rambus’ first European patent.”

Two technical experts were appointed last year by the Monza Court in Italy to evaluate the infringement of Rambus’ patent by Micron’s SDRAM products. Their technical examinations lasted over five months encompassing all pertinent prior art information and potential infringement of the Rambus patent by the Micron SDRAM products.

According to Rambus, the court-appointed experts produced an exhaustive report, confirmed the validity of the Rambus patent in suit and determined that Micron’s SDRAM products infringe the Rambus patent.
