Abstract

PURPOSE: To increase the number of bits for each word and then reduce the number of signal terminals, by using the address information of the writing mode in the form of the retrieving mode.
CONSTITUTION: An associative process is carried out between the retrieving data and the memory information stored in the memory, and the result of this associative process is delivered in correspondence of words. In this case, the mode designation signal 11 becomes 1 in the read/write mode to activate the gates 7W10, and the output of the decoded 2 address information is connected to the designated word line among 12W 15 to perform the reading and writing via the input/output data line 17. On the other hand, in the retrieving mode, the signal 11 becomes 0 with the word lines 12W15 turned to 0, and the associative memory cell arrays 18W21 compare the retrieving data applied to the retrieving data line 16 with the memory data. And 1 is delivered to the detection signal lines 22W25 when a coincidence is obtained in the above comparison.
