Sample status for
top-density synchronous SRAMs

Cypress Semiconductor has begun shipping samples of the world's highest-density synchronous SRAMs

The 72Mbit, six-transistor (6T) devices, supporting standard synchronous and NoBL (no bus latency) architectures, are designed for high-data-throughput, low-latency applications, including switching, routing, basestations and data storage. "Cypress has leapfrogged the competition at 72Mbit, giving our customers the ability to dramatically improve the performance of their networks", said Antonio Alvarez, Senior Vice President for Cypress's Memory Products Division.

"Cypress's new high-density SRAMs are designed into switches and routers, enabling networks, like the Internet, to run more efficiently and with greater capacity".

Available in 42 different configurations, Cypress's CY7C147X- and CY7C148X-series SRAMs deliver data five to seven times faster than competing high-speed DRAMs.

Innovative design techniques significantly improve power consumption, speed and manufacturing flexibility.

The devices are pin compatible with lower-density SRAMs, enabling easy migration to higher densities by simplifying designs and saving board space.

Cypress's new 72Mbit products can be purchased with either pipelined or flowthrough architectures.

With the pipelined architecture, they support clock speeds of up to 250MHz and provide up to 9Gbit/s bandwidth with one clock cycle of initial latency.

Using advanced frequency detecting circuitry, these devices are able to provide valid data during more than 60% of every clock cycle with a data valid window from 2.4 to 4.1ns, maximising its customers' timing budgets.

Products designed with the flowthrough architecture support clock speeds of 133MHz, providing up to 4.8Gbit/s of bandwidth with less than one cycle of initial latency.

Both pipelined and flowthrough devices are offered in 3.3 and 2.5V BGA, FBGA or TQFP packages, and are available in 4M x 18, 2M x 36 or 1M x 72bit configurations.

Cypress's 72Mbit devices are its first to use its leading-edge 90nm (0.09-micron) RAM9 process technology at its Fab 4 facility in Bloomington, Minneapolis.

This technology uses Cypress's patented fully self-aligned contact and a tungsten stacked gate, which enables high performance transistors that are scalable to future technologies.

"This is a major breakthrough for Cypress's process technology development", said Alvarez.

Cypress's CY7C147X- and CY7C148X-series SRAMs are priced at $95 in 5000-unit quantities.

Full production will commence in Q4.
