Advanced Micro Devices (AMD) Inc. has signed licensing agreements with two subsidiaries of Acacia Research Corp. to settle outstanding patent infringement suits.

First, AMD signed a license agreement with Computer Cache Coherency Corp., a wholly owned subsidiary of Acacia that covers a portfolio of patents for certain core logic computer chipsets, resolving a patent suit pending in the District Court for the Northern District of California.

The core logic technology relates to interface circuits used by intelligent peripheral devices with cache memory to communicate with the main computer memory, Acacia said.

By synchronizing main computer memory and main cache memory, the company said the technology enables different memories to communicate and synchronize with each other, allowing peripheral devices to operate at faster speeds, and can be used in desktop, notebook, and server computer systems.

“The agreement with AMD is the first license for our Computer Cache Coherency technology,” said Paul Ryan, chairman and CEO of Acacia, in a statement. “We have now generated revenues from 11 different patented technologies so far this year, as we continue to expand our revenue base.”

Acacia also said Computer Cache Coherency has patent enforcement litigation for this technology pending in the District Court for the Northern District of California against Intel Corp. and Via Technologies Inc.
