AMD signs $75M patent license agreement with Rambus

Chip maker AMD has signed a five-year, US$75 million patent license agreement with Rambus for patents used in memory and logic controller interfaces.

Chip maker Advanced Micro Devices (AMD) has signed a five-year, US$75 million patent license agreement with Rambus, the technology licensing company announced Tuesday. Under the terms of the deal, Rambus will provide AMD with a license to Rambus patents used in the design of memory and logic controller interfaces.

The license includes Rambus patents used in the design of DDR2 (double data rate 2), DDR3 (double data rate 3), FB-DIMM (fully-buffered dual in-line memory module), PCI (peripheral component interconnect) Express and XDR (extreme data rate) controllers along with other current and future high-speed memory and logic controller interfaces, according to a Rambus release issued Tuesday. The agreement covers all chips except for memory chips. The arrangement can be renewed or extended.

The agreement between the two companies is new, according to a Rambus spokeswoman. Rambus already has a long-standing patent license agreement in place with AMD rival Intel. The most recent agreement with Intel was signed five years ago and is set to expire in the middle of this year, the spokeswoman said. The agreement with Intel is also renewable.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
