Abstract

Memory cells disposed in a matrix are divided into a plurality of blocks. Each block is constructed of n (n is a positive integer larger than 2) memory cell columns. One block is selected by one column address. One memory cell column in the n memory cell columns in a selected block is selected by a first gate. One memory cell column in the n memory cell colunns in a selected block is selected by a second gate. One memory cell in a selected memory cell column is selected by a row address. The data in a selected memory cell are stored in a register and output therefrom.
