SAN JOSE -- NEC Corp. today announced it was joining Cypress Semiconductor Corp. and Micron Technology Inc. to support new Quad Data Rate (QDR) static RAMs for high-performance memories in switches, routers, and other systems applications with data rates above 200 MHz.
Cypress, Micron, and Integrated Device Technology Inc. announced the QDR SRAM specifications in 1999 to make available compatible products from multiple suppliers (see July 26, 1999, story). NEC joins the group in co-developing QDR SRAM product specs for pin- and function-compatible products.
"It is the most viable means to achieve the high-bandwidth memories required by the next wave of high-speed data networks," said Zensuke Matsuda, general manager of NEC's 2nd LSI Memory Division in Japan. "We are committing to this specification because it drives the development of the memory products our customers need to design their future data networking systems."
The QDR SRAM architecture has two ports that independently run at double data rate (DDR), resulting in four data items per clock cycle. Depending on the applications, QDR SRAMs can more than double the SRAM bandwidth, according to QDR SRAM suppliers.
