Abstract
A semiconductor memory device for driving word lines at high speed has a word line signal generating circuit for receiving a predecoded signal of a row address, and power source supply circuit for supplying the output signal of the word line signal generating circuit to a word line as source power. The device includes a normal word line decoder for receiving the predecoded signal and the output signal of the power source supplying circuit, respectively and for selecting a normal word line; a spare word line decoder for receiving the predecoded signal and the output signal of the power source supply circuit, respectively and for selecting a spare word line; and a redundancy enabling circuit connected to the spare word line decoder and the normal word line decoder for determining whether the normal word line is selected.
