36-Bit Dual-Port SRAMs Claim Speed Record

In an effort to create the industry’s fastest 36-bit dual-port SRAM family, the firm has increased the speed of its 3.3V synchronous dual-port SRAM devices to 133 MHz. In addition, the enhanced devices include selectable 3.3V or 2.5V I/Os on each port, providing flexibility for designers wanting to develop mixed-voltage systems. And because these dual-port memories provide a direct interface between mixed-voltage components, designers can easily combine 2.5V devices, such as DSPs and network processors, with 3.3V technology circuits. Also, the simultaneous access of data from two ports, combined with the 36-bit-wide bus and 133-MHz operation, allows system designers to achieve 9.6 Gbps bandwidth, moving the devices into contention for data-intensive applications, such as ATM and Ethernet switches and routers. The dual-port SRAMs are available in PQFP, TQFP and fine-pitch BGA packages.
