Rambus said Tuesday it has signed a five-year licensing agreement with Advanced Micro Devices, giving AMD a license to Rambus patents.

Rambus is a technology licensing company, while AMD is a major semiconductor manufacturer.

The license includes Rambus patents used in the design of DDR2, DDR3, FB-DIMM, PCI Express and XDR controllers as well as other current and future high-speed memory and logic controller interfaces.

The five-year term of the agreement carries the possibility of renewal or extension. Specific terms of the agreement were not disclosed.

"The license of our patent portfolio with AMD's demonstrated innovation in the microprocessor market is highly compelling," Harold Hughes, chief executive officer at Rambus, said in a news release. "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," he added.
