8K Words x 9 Bits High-Speed CMOS Static Random Access Memory with Automatic Power Down
The Fujitsu 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 c Olumn addresses, making it very suitable to use as cache buffers. To make power dissipation lower, peripheral circuits use CMOS technology, and to obtain smaller chip size, cells use NMOS transistors and resistors. All pins are TTLpatible and asingle +5 Vpowersupply is required.
The MB81 C79B offers low power dissipation, low cost, and high performance.
