NEC joins quad-data-rate SRAM team

NEC is joining with three US-based memory firms, Cypress Semiconductor Corp., Integrated Device Technology Inc., and Micron Technology Inc., to develop and then make quad-data-rate (QDR) static RAM this year. QDR SRAM architecture uses two ports running independently at a double data rate, producing four data transfers each clock cycle. QDR SRAMs will reportedly more than double SRAM bandwidth and are aimed at the Internet switching and router market.

In related news, Rambus Inc. is scheduled to show its own quad-speed signaling technology (QRSL) at the DesignCon 2001 show this week. According to Rambus, the technology "combines the patented double data rate (DDR) technology along with multi-level signaling to transfer four bits per clock cycle."
