82S112 Overview

The 82S12/112 is a Schottky TTL 32 bit multiport memory organized in 8 words of 4 bits each. The device is ideally suited for high speed accumulators and buffer memories. Stored data is addressed through 2 independent sets of 3-input decoders, and read out when the corresponding output enable line is low.
