PROBLEM TO BE SOLVED: To provide a word line driving circuit in which memory yield can be improved by making a main word line driver signal floating in a pre-charged state and suppressing increase of a standby current caused by resistive connection of adjacent power source wirings. SOLUTION: In a word line driving circuit consisting of a main word line driving circuit generating a word line driving signal and a control circuit generating a control signal controlling this circuit, the main word line driving circuit comprises such control means that turns on the pull-up transistor for a fixed time at the time of input of a pre-charge command, turns on the pull-down transistor, so that the word line driving signal is pre-charged to a high state, on the other hand, after pre-charging, the pull-up transistor and the pull-down transistor are turned off, and the word line driving signal is made floating.
