ABSTRACT:
In a semiconductor memory device including: a plurality of sub word lines, a plurality of sub word decoders each connected to one of the sub word lines, a plurality of pairs of main word lines each pair connected to a number of the sub word decoders, and a plurality of main word decoders each connected to one of the pairs of main word lines, each of the main word decoders sets voltages at a respective pair of the pairs of main word lines different from each other in a selection mode and sets the voltages at a respective pair of the pairs of main word lines the same as each other in a non-selection mode.
