Rambus Unveils Redwood, the Industry's Fastest Parallel Bus Logic Interface

Interface family is capable of running up to ten times faster than best-of-class processor busses with backward compatibility to existing standards

INTEL DEVELOPER FORUM, SAN JOSE, CA, Feb. 17, 2003 - Rambus Inc. (Nasdaq: RMBS), a leading developer of chip-to-chip interface products and services, today introduced its parallel bus logic interface family, codenamed Redwood. Ideal for high volume, low-cost systems, the Redwood family of interface products offers a per pin data rate of 400MHz to 6.4GHz, enabling it to run up to ten times faster than best-of-class processor busses available today.

The Redwood parallel bus interface family addresses intra-board applications including processor, chipset and network chip connections. It is optimized for low latency and low power parallel bus applications, and enables the highest-pin bandwidth to reduce overall package, board, and system costs. Additionally, Redwood can be backwards compatible with existing LVDS-based standards such as HyperTransport, SPI-4 and RapidIO, allowing for easy integration into next-generation products. In order to achieve backwards compatibility, Redwood offers customers a range of frequency and voltage support.

"Redwood technology is a perfect addition to our portfolio of logic interface solutions as it provides our customers with high performance, parallel bus connections that complement our RaSer family of high-performance serial link interfaces," said Kevin Donnelly, vice president of Rambus' Logic Interface Division. "Furthermore, Redwood's flexible and scalable architecture allows us to customize solutions to further enhance the performance of our customers' products."

Elements integrated into the Redwood technology include a 400 MHz-6.4 GHz data rate range, low-voltage differential signaling, backwards compatibility with existing standards, FlexPhase timing calibration circuit technology, and dynamic current and termination capabilities. Combined, all of these technologies allow Redwood to achieve up to 6.4 GHz speeds for low-cost systems.

The Redwood family of parallel bus logic interfaces is available now for licensing. Rambus will be disclosing more technical detail and usage of Redwood at the Intel Developer Forum on Thursday, February 20 at 3:30 pm at the San Jose Convention Center.
