Abstract

PURPOSE: To produce the large-capacity memory elements with a high yield as well as to lower the action error probability of the memory element by installing both the error correction circuit and the circuit selecting the input and output data within the memory element.
CONSTITUTION: The stored information in shift registers 01W07 are read out 10W 16 in sequence, and the error correction code in the output is tested through correction circuit 20 to be then corrected. After correction, the information bit is delivered to lines 21W27. In case no indication is given to the writing action, data selection circuit 40 supplies the information bits of lines 21W24 to writing circuits 80W83 via lines 42W45. At the same time, the check bits of lines 25W27 are supplied to check bit writing circuits 84W86. On the other hand, with application of writing order W, circuit 40 supplied input data Din to circuits 80W83 in accordance with address signals A0WAn-1. And the information bit delivered from circuit 40 is transmitted via buffer 60.
