Abstract
According to an embodiment, a word line driver includes: a first inverter that is driven by a first power supply voltage and inverts and outputs a decode signal; a second inverter that is driven by a second power supply voltage and inverts and outputs the decode signal; a first PMOS transistor that is controlled to be turned on or off on the basis of an output signal of the second inverter; a first NMOS transistor that is controlled to be turned on or off on the basis of an output signal of the first inverter; and a second PMOS transistor that is provided between a power supply voltage terminal to which the second power supply voltage is supplied and the gate of the first PMOS transistor and is temporarily turned on in synchronization with falling of the decode signal.
