Abstract
A semiconductor memory device for sequentially disabling activated word lines is provided. The semiconductor memory device having a plurality of word lines connected to a plurality of memory cells includes a predecoding unit for predecoding a row address received from the outside, a row decoding and word line driving block, which is connected to the predecoding unit and the plurality of word lines, for decoding an output of the predecoding unit, selecting some of the plurality of word lines, and activating the selected word lines and a controller connected to the predecoding unit and the row decoding and word line driving block, for receiving the row address, the output of the predecoding unit, and at least one control signal, generating at least one output signal, and sequentially disabling the activated word lines by enabling the at least one output signal in response to the row address and the output of the predecoding unit.
