Broad choice and high performance in multi-port memories

Designers can choose from more than 160 synchronous and asynchronous dual-port SRAMs from Cypress Semiconductor for inter-processor communications and single-processor companion memory, with a variety of densities and bus widths to suit processor and system parameters.

Within the Cypress portfolio, the latest FullFlex™ family provides built-in features that simplify board design and support high-bandwidth data transfers between processing elements. These include Double Data Rate (DDR) capability, which doubles system throughput without increasing pin count. Other features include variable impedance matching, deterministic access control, selectable I/O standards and echo clocks. Burst counters and collision-detection features also help designers manage and optimise data exchanges.

FullFlex dual-port SRAMs also deliver high performance as companion memory in single-processor configurations. By operating at frequencies up to 250MHz, they can provide 36Gbit/s of dedicated memory bandwidth independent of the system read-to-write ratio.

A variety of bus widths are available, including x72 devices offering easy interoperability with 64-bit processors. Other bus widths available are x8, x9, x16, x18 and x36. FullFlex devices are also pin-compatible with previous generations of Flex-family dual-ports from Cypress, allowing legacy designs to quickly take advantage of the enhanced FullFlex feature set.
