Rambus PCI Express PHY IP on Fujitsu 90nm CMOS Process

Compliance and interoperability tested, silicon proven PHYs extend to multiple applications

LOS ALTOS, California, United States - 7/5/2005   Rambus Inc. (Nasdaq:RMBS), one of the world’s premier technology licensing companies specializing in high-speed chip interfaces, today announced the availability of Rambus’s PCI Express* PHY in Fujitsu’s 90nm CMOS process.

The Fujitsu 90nm CMOS process addresses applications requiring very high integration with a small form factor, low power consumption and low leakage current. It meets the low power consumption and multi-functionality design challenges of the mobile device market, as well as the high performance design needs of leading-edge network, server and telecommunication applications.

“By offering the Rambus PCI Express PHYs on their 90nm process, Fujitsu continues to strengthen its foundry position,” said Laura Stark, vice president of Platform Solutions at Rambus. “Development teams will now be able to manufacture PCI Express-based chips on Fujitsu’s leading, state-of-the-art fab for a wide range of system applications.”

The Rambus PCI Express PHY is a complete serial communication cell optimized for implementing the physical layer of the PCI Express standard. Rambus’s PCI Express PHY design is in production in various high-volume applications such as PC graphics, chipsets, switch and bridge chips. It is supported by a comprehensive suite of digital controllers and support services to provide chip developers with a complete system solution. Rambus PCI Express PHYs are listed on the PCI-SIG Integrators List, having passed PCI-SIG compliance and interoperability testing by Rambus PHY cell customers and digital controller partners. The PCI-SIG is the special interest group that owns and manages PCI specifications as open industry standards.

“As part of our wafer foundry services, our goal is to offer access to leading IP in addition to complementary services such as test and packaging. With Rambus’s PCI Express PHY IP, our customers now also have access to the market’s leading PCI Express physical layer solution,” said Tatsuya Yamazaki, general manager of Foundry Marketing at Fujitsu Limited. “With the addition of Rambus’s PCI Express PHY IP into the Fujitsu IP portfolio, we are now able to offer optimum solutions to high-end oriented customers.”

Designs for PCI Express based chips with the Rambus PCI Express PHY may now be submitted for manufacture in Fujitsu’s 90nm process technology. For more information on the availability of licensing the Rambus PCI Express PHY, visit www.rambus.com/products.
