SAN JOSE -- Cypress Semiconductor said it was sampling what it claims is the industry's first 9-Mbit dual-port RAM.
The CY7C08D53 is aimed at the memory buffering requirements of high-performance wide-area networks, storage networks and wireless basestations.
It is said to provide 9 Mbits of synchronous, pipelined dual-ported memory capable of buffering large packets of data in two independent clock domains. Configured as a 256K x 36 bit wide device, it provides up to 6 Mbps of bandwidth and allows for easy interface to wide busses, Cypress said.
The device operates at up to 83 MHz, staying ahead of the popular PCI bus speed sweetspot of 67 MHz, according to the San Jose-based company. It will be packaged in a 176-pin TQFP (24mm x 24mm).
The device is said to provide simultaneous read and write access to any memory cell in its 9 Mbit memory array from either of its two ports. In addition, the two ports may operate in completely independent clock speeds, allowing complete decoupling of the devices being interfaced, the company said.
Alpha samples of the CY7C08D53 are available now and production quantities will begin shipping in the second quarter. The devices will be priced around $97 in quantities of 10K units.
