|RAMBUS and UMC Expand Availability of RAMBUS PCI Express PHY IP for a
Broader Range of Process Technologies|
LOS ALTOS, Calif. and HSINCHU, Taiwan - Rambus Inc.
and UMC announced that they have extended the availability of Rambus's patented PCI Express PHY cells to UMC's
180nm, 150nm, and 90nm processes. This development expands on the existing 130nm licensing agreement between the two
companies, which was signed in 2004.
Under the agreement, UMC foundry customers gain access to Rambus's broad
portfolio of PCI Express-based interfaces. The Rambus PCI Express PHY cells have been designed to provide chip
developers with a solution that optimizes link utilization, latency, power consumption and silicon footprint. The
PCI Express interface standard is one of the industry's most successful for chip-to-chip interconnects and can be
found in system applications ranging from supercomputers to PCs and digital TVs.
currently in production with Rambus's PCI Express PHY cells include the high-volume PC chipset manufacturers ULi
Electronics and the high-volume PC graphics manufacturer XGI Technology, Inc. Rambus PCI Express PHY cells are also
in production in various bridge and communication IC products based on the UMC foundry process.
"By partnering with UMC, Rambus continues to enable mass adoption for advanced interface technology that
results in faster, lower cost, and more capable systems," said Laura Stark, vice president of Rambus's Platform
Solutions Group. "In addition, the availability of this combined offering helps chip and system developers bring new
capabilities to market with lower risk."
"We are pleased to expand our licensing agreement with
Rambus to make its proven IP solutions available to a broader range of technologies, including our mainstream 90nm
process," said Ken Liou, director of UMC's IP and Design Support Division. "This agreement allows our customers
designing SoCs targeting PCI Express applications to benefit from Rambus's broad offering of PCI Express PHY
Rambus PCI Express PHYs are complete serial communication cells optimized for
implementing the physical layer of the PCI Express standard. The silicon-proven serial interfaces feature
point-to-point, full duplex signaling and support up to a 3.2Gbps data rate. Rambus has also demonstrated its Turbo
PCI Express platform with serial links operating at 5.0Gbps and 6.25Gbps data rates to meet future PCI Express
requirements. 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. The Rambus PCI Express
PHY cells are supported by a comprehensive suite of digital controllers and support services to provide chip
developers with a complete system solution.
