signed a five-year agreement with
Advanced Micro Devices
that grants the chipmaker a license to certain patents used in the design of memory and logic interfaces.
The agreement also includes the possibility of a renewal or extension. Specific financial terms weren't disclosed, but
quoted a Rambus representative who said the AMD pact would be worth around $15 million a year.
"The license of our patent portfolio with AMD's demonstrated innovation in the microprocessor market is highly compelling," said Harold Hughes, chief executive at Rambus. "We are very pleased to start the new year with an agreement that reflects a new approach for pricing our controller licenses and to continue to provide the market with innovative high-speed chip interface technologies."
Rambus, of Los Altos, Calif., designs memory interfaces for microchips, which it then licenses out to semiconductor makers. Shares of Rambus were climbing $1.58, or 9.8%, to $17.77 Tuesday. AMD added 69 cents, or 2.3%, to $31.29.
