ABSTRACT:
An associative memory device in which a detection or determination is made if the same information as that to be written in the associative memory cells has been stored therein before storing the information to be written in the memory cells, and if the result of the detection is that the same information has been stored therein, the information to be written is inhibited from being stored while when the same information has not been stored therein, the information to be written is permitted to be stored in a predetermined memory cell, so as not to store the same information into a plurality of different addresses of the memory cells.
