Fujitsu MB81C79B
MB81C79B is a 8,192 words x 9 bits static random access memory fabricated with CMOS technology. The 9-bit organization of this device is desirable for use in a parity checkfunction. This device also has two fast cOlumn addresses, making it very suitable to use as cache buffers.ABSOLUTE MAXIMUM RATINGS
