Product Summary

The CY7C146-25JC is a 2K × 8 dual-port static RAM. The CY7C146-25JC provided to permit independent access to any location inmemory. The CY7C146-25JC can be utilized as either astandalone 8-bit dual-port static RAM or as a MASTERdual-port RAM in conjunction with the CY7C146-25JC dual-port device in systems requiring 16-bit or greaterword widths. The CY7C146-25JC is the solution to applications requiring sharedor buffered data such as cache memory for DSP, bit-slice, ormultiprocessor designs.
