ABSTRACT:
A semiconductor memory device capable of improving the operating speed while suppressing size increase is provided. This semiconductor device comprises a plurality of word lines and a plurality of bit lines arranged to intersect with each other, a single-port SRAM cell, connected to the bit lines and the word lines, having a single port for inputting/outputting data, a first row decoder and a second row decoder connected to the word lines for selecting a row address and a first column decoder and a second column decoder connected to the bit lines for selecting a column address, while each word line is divided into a plurality of local word lines.
