Abstract

PURPOSE:To reduce the number of write-in cycles and to decrease the write-in time, by storing the write-in data in the storage circuit to perform simultaneous write-in of a plurality of words. CONSTITUTION:The write-in information via an I/O section 15 is stored also in a pre-storage circuit 16, and the write-in information to cell blocks 2-1, 1-2 is stored in the I/O section 15 and the circuit 16. The write-in information is simultaneously written in the same address cells C12, C22 of blocks 2-1, 1-2 via transistors W1, W2. Further, the readout is made one by one word with any of transistors Q1, Q2. Accordingly, a number of pre-storage circuits are provided, then simultaneous write-in of a plurality of words can be made, allowing to reduce the number of write-in cycles and to decrease the entire write-in time.
