7/16/2002 - The QDR™ SRAM co-development team today announced the Network Processing Forum (NPF) has adopted key elements of the Quad Data Rate™ (QDR™) interface as the standard for Phase 1 of the Look–Aside Interface (LA-1). The LA-1 specification passed the NPF’s Principal Member Ballot on May 24, 2002. QDR SRAM is a high-performance communications memory standard for network switches, routers, and other communications applications.
The NPF was organized to facilitate and accelerate the development of next-generation networking and telecommunications products based on network processing technologies. The LA-1 Interface is designed to offload certain tasks from the Network Processing Unit (NPU) and is targeted primarily, though not exclusively, at memory-based lookup coprocessors. QDR SRAM is one of the high-performance technologies on which LA-1 is based.
“One of our goals is to utilize, as much as possible, existing technologies,” said Misha Nossik, Chairman of the NPF Board of Directors. “Basing NPF implementation agreements on a proven technology helps reduce implementation risk while maximizing flexibility for end customers and NPE vendors.”
“QDR’s adoption, innovation, and market growth continues to make the QDR SRAM family of products the high performance memory of choice in the networking market. We feel this standard will be beneficial to both our networking customers and integrators,” said Mario Martinez, director of Strategic Marketing for Cypress’s Memory Products Division. “The QDR SRAM Co-Development team continues to gain momentum in the networking marketplace with QDRII, its next-generation family of products.”
Many companies developing and using memory devices are currently using the QDR SRAM standard. Since most leading memory vendors participated in the LA-1 specification development, users can be confident that the LA-1 specification meets real-world needs.
The QDR SRAM Co-Development Team is collaborating to define proprietary networking SRAM architectures. The leading team members include Cypress, Micron, IDT, NEC, and Samsung. Hitachi has signed a letter of intent to join the QDR SRAM Co-Development Team.
In 1999, the QDR SRAM Co-Development Team was created to define a new family of SRAM architectures for high-performance communications applications. Participating companies work closely together to ensure multiple sources for the new QDR SRAMs by developing pin- and function-compatible products. The QDR family of SRAM products incorporates extensive input from networking industry leaders. QDR SRAM devices have two ports running independently at twice the rate of conventional synchronous memories, resulting in four data items per clock cycle. The QDR SRAM family of products includes Quad Data Rate and Double Data Rate common and separate I/O definitions. Depending on the application, products in the QDR SRAM family can more than double SRAM device efficiency per pin.
