ABSTRACT:
A semiconductor memory device includes a memory cell array divided into a plurality of blocks respectively having bit lines, word lines, and memory cells coupled to the bit lines and word lines. A plurality of sense amplifiers, which are provided for the blocks and connected to the bit lines, sense and amplify information stored in the memory cells. A first unit selects one of the word lines for each of the blocks so that at least one of selected word lines is located at a distance from a corresponding one of the plurality of sense amplifiers. The above distance is different from distances from other sense amplifiers at which other selected word lines are located. A second unit sequentially activates the plurality of sense amplifiers, starting from one of the blocks having one of the selected word lines located at a shortest distance from a corresponding one of the plurality of sense amplifiers.
