Renesas Technology Introduces Highest Level Performance 72-Mbit QDR™ II+ SRAM and DDR™ II+ SRAM Family

SAN JOSE, Calif. — (BUSINESS WIRE) — July 7, 2009 Renesas Technology America, Inc., today announced the 72-Mbit Quad Data Rate II+ (QDR™ II+) and Double Data Rate II+ (DDRII+) high-speed SRAM*1 product family for use in high-end routers and switches in next-generation communication networks. These SRAM products achieve the industry's fastest level operating speed and are compliant to the QDR Consortium*2 industry standard. Additionally, this release also includes 72-Mbit QDRII and DDR II SRAM devices. The full range of devices, consisting of multiple speeds and configurations, will be available beginning in August 2009.

These new products offer the following features.

(1)   Achievement of the industry's fastest level operating speeds: 533 MHz for the QDRII+ and DDRII+ SRAM and 333 MHz for the QDRII and DDRII versions
For these products, Renesas greatly increased the operating speeds, while maintaining low-voltage operation, by utilizing the advanced 45 nm fabrication process. The QDRII SRAM products achieve the industry's highest operating speed level of 333 MHz, and the QDRII+ SRAM products also provide the industry's highest operating speed level of 533 MHz. These devices can support high-speed processing for packet look-up and packet buffer applications in high-end routers and switches that support 10G, 40G, and beyond multi-layer communication systems.
(2) Broad portfolio of 72-Mbit devices

Renesas will provide products that support three data I/O widths (9, 18, or 36 bits) and two burst lengths (2 or 4 words). In addition, Renesas will also provide products that feature a built-in ODT (on-die termination) function that significantly reduces the signal quality degradation that can occur during high-speed operation. Renesas' extensive lineup of QDRII, DDR II, QDRII+, and DDRII+ SRAM products allows users to select solutions that are optimal for their systems.

< Product Background

With the ever-growing popularity of the Internet, transmission speeds and the amount of traffic being sent to communication equipment continue to increase, with data rate speeds now exceeding 40-Gbits/second. Checking data destinations and managing data packet traffic in high-end networking equipment is driving the demand for high density memory capable of high speeds. Furthermore, the complexity of data continues to increase with video, voice, and data applications, requiring even larger memory capacities.

“Renesas Technology currently provides a broad range of SRAMs for industrial applications and for cache memory in UNIX*3 servers and workstations, and 18-Mbit Network SRAM and 36-Mbit DDRII and QDRII SRAM for communication equipment,” said Rob Raghavan, sr. marketing manager for the Solutions Business Unit, Renesas Technology America, Inc. “As network equipment evolve to higher levels of performance and capability, Renesas Technology has leveraged its design expertise and manufacturing technologies to achieve higher speeds and high reliability for the 72-Mbit QDR II+ and DDR II+ SRAM products to meet the demands for higher speed, larger capacity, and greater bit widths required for communication applications.”
