ABSTRACT:
In a block access memory in which the memory cell array is divided into a plurality of blocks and data input/output is carried out by block unit, each block is divided into a plurality of subblocks, and the timing of activating the word line and the timing of activating the sense amplifier are made different for each subblock in the block in which the selected word line is included, whereby the peak current associated with the bit line charge/discharge at the time of activating the sense amplifiers is reduced.
