Abstract
A read/write/restore circuit is disclosed for use in a memory array such as a static RAM array. The circuit employs data and data-complement signals having three states in combination with a two-state address signal to perform read, write and restore functions for the array, to reduce the number of components and control lines needed. The circuit is preferably implemented in BICMOS technology.
