QuadPort RAM has bandwidth for comms

Cypress Semiconductor has announced the availability of production volumes of its 1Mbit QuadPort RAM, the next-generation bandwidth optimised family of synchronous memories.

Cypress Semiconductor has announced the availability of production volumes of its 1Mbit QuadPort RAM, the next-generation, bandwidth-optimised family of synchronous memories designed for WAN and SAN markets.

The family was developed in conjunction with EMC, the world's leading provider of information storage infrastructure systems, for a new storage application.

The QuadPort RAM's four completely independent ports can simultaneously access its 1Mbit (64K x 18bit) memory array and operate in different frequency domains.

Each port can write at 133MHz, giving the device up to 9.6Gbit/s of data throughput or bandwidth.

The QuadPort RAM provides simultaneous access to the memory array by up to four separate processors, ASICs, complex programmable logic devices (CPLDs), physical layer transceivers (PHYs) or buses.

The device can be used in innovative ways to enhance the architecture of high-performance communications systems.

In a typical application it can function as a four-ported (2 x 2) shared memory switch fabric, a 3:1 or 1:3 buffered MUX/DEMUX, a packet snooping engine for packet header manipulation, or a redundant data path generator for fault-tolerant systems.

"The 1Mbit QuadPort RAM empahsises Cypress's commitment to provide innovative, high-bandwidth and high-density solutions in specialty memories, targeted at the needs of the communications market", said Christopher Norris, Cypress vice president of data communications.

"This device will cause system designers to view specialty memories as a critical component of their architecture, rather than just a memory buffer afterthought.

The collaboration between Cypress and EMC helped Cypress create the best QuadPort RAM product for the communications marketplace, and helped EMC solve many critical design issues".

Cypress offers several families of high-performance, deep and wide speciality memory devices.

The company's high-bandwidth memories address the demands of WANs, wireless infrastructure equipment and storage applications.

They are also used to facilitate the transfer and storage of the volumes of data required by the growing number of end-users on the Internet.

Bandwidth, the amount of data throughput of a device, can be increased on a memory by several methods: increasing the number of access ports, widening the word width of devices, increasing clock speeds, or any combination of these methods.

Currently at the 10Gbit/s performance level, Cypress aims to achieve 25Gbit/s in the near future.

The 1Mbit QuadPort RAM (CY7C0430V) is offered in a 272-ball BGA package measuring 27 x 27mm with a 1.27mm lead pitch.

Production quantities are available now, priced at $98.00 in volumes of 10,000.
