Abstract

A memory cell circuit of an associative memory composed of only four NMOS transistors is disclosed. Each memory cells of the circuit is connected two bit lines, a word line, a match setup line for commanding coincidence detection, and a match line for transferring the results of detection. The data signals are stored in the gate capacity of each of the transistors 3. This simplified memory cell circuit contributes to higher integration of the associative memory.
