Abstract
There are provided a plurality of CMOS configured pre-driver circuits, wherein an increased voltage obtained by increasing a power voltage is applied to a source of each P-channel transistor, and a word line driver circuit each having a P-channel transistor and an N-channel transistor to which an output of the pre-driver circuit is inputted. The source of each N-channel transistor in the plurality of pre-driver circuits is connected in common to that of each N-channel transistor in the word line driver circuit, and a source-drain path of an N-channel transistor for voltage alleviation is connected between this source common node and a node of a grounding voltage. The increased voltage is applied to a gate of the N-channel transistor for voltage alleviation.
