Abstract
A semiconductor memory device is provided having reduced power consumption during a normal operation. The semiconductor memory device includes a sub word-line defined by segmenting a word-line and a driving signal generator for selectively driving the sub word-line according to a column address. The driving signal generator is controlled by a selection signal corresponding to the column address and a mode signal for specifying an operation mode of the semiconductor memory device. The semiconductor memory device enables part of the word-line according to the column address. The semiconductor memory device using a sub word-line driver to reduce the number of memory cells which are sensed, thereby reducing power consumption.
