(Nasdaq:RMBS), the leading provider of high bandwidth chip connection technologies, disclosed details of recent advances in Direct Rambus(TM) and QRSL(TM) interface technologies in two presentations at the International Solid-State Circuits Conference (ISSCC) being held from February 5-7, 2001 in San Francisco, Calif. The first presentation, titled "Circuit Design for a 2.2GB/s Memory Interface", addressed a high-speed 2.2 Gigabyte per second (GB/s) signaling interface for main memory which uses a DLL that enables in-system timing calibration with 1.4 degree resolution and uses output drivers with limited positive feedback to increase voltage margin. Rambus engineers disclosed technical advancements to the signaling interface demonstrating prototype chips operating at up to 2.6 GB/s in a standard CSP package. Direct Rambus technology enabled the DRAM industry's highest level of performance to date -- 1.6GB/s of peak bandwidth from a single device. The Direct Rambus interface achieves its unprecedented performance through circuit advances and architectural extensions. The second presentation highlighted a 25% increase in bandwidth of Rambus' QRSL signaling technology to a transfer rate of 2 Gigabits per second per pin (Gb/s/pin). In addition, the paper demonstrates the first disclosure of an operational four-slave configuration. Titled, "A 2Gb/s/pin 4-PAM Parallel Bus Interface with Transmit Crosstalk Cancellation & Equalization and Integrating Receivers," this presentation detailed the design of a 2Gb/s/pin single-ended 4-PAM interface and showed measured system margins in a test system representing a low-cost consumer environment.
