Product Summary
The CY7C130-55DMB is a high-speed CMOS 1K by 8 dual-port static RAM. One port is provided permitting independent access to any location in memory. The CY7C130-55DMB can be utilized as either a standalone 8-bit dual-port static RAM or as a master dual-port RAM in conjunction with the CY7C130-55DMB slave dual- port device in systems requiring 16-bit or greater word widths. It is the solution to applications requiring shared or buffered data, such as cache memory for DSP, bit-slice, or multiprocessor designs.
