Los Altos, California, United States  and  Langon, France  - 04/17/2007   Rambus Inc. (NASDAQ:RMBS), one of the world's premier technology licensing companies specializing in high-speed chip architectures, and TES Electronic Solutions (TES), the global electronics design and manufacturing services company, today announced a joint marketing agreement to deliver comprehensive and synergistic design solutions. The partnership expands the customer support for Rambus intellectual property (IP) through TES’ extensive network of worldwide design centers. Under the agreement, TES will market and integrate Rambus IP products as part of its IC and system designs.

The scope of this agreement is initially directed towards the European market with a focus on customers in the networking, telecom, and automation industries. These companies can benefit from Rambus’ leading-edge IP solutions including a broad line of digital cores for PCI Express*, Ethernet and Rapid IO and the related serial link PHYs.

“Rambus is the recognized leader in high-performance serial link and memory design, and having access to their innovative and proven IP products greatly expands our offerings for our growing customer base,” said Michel Desbard, president and CEO at TES Electronic Solutions. “Our customers demand high-quality, easy-to-integrate intellectual property solutions, and the combination of Rambus’ superior technology and TES design services offers them great value.”

With the rapid proliferation of PCI Express beyond computing, and into embedded applications such as communications and automation, there is a strong market need for high-quality IP that can be adapted to varying application needs and is easy to integrate. Rambus digital IP cores meet these needs by being highly configurable and rigorously validated using extensive simulation and hardware validation methodologies as well as industry-leading third party verification IP.

“Our partnering with TES provides European customers access to Rambus IP products backed by TES experts who can help them efficiently integrate these products into their designs,” said Sharon Holt, senior vice president, worldwide sales, licensing and marketing at Rambus. “We have seen great momentum for our IP products in Europe, and TES has the right expertise to serve our growing European customer community.”
