Abstract
A plurality of switches composing a voltage changing switch circuitare supplied with a plurality of types of voltages, and are provided so as to correspond to a plurality of row decoders, such that each switch can separately select and output any of the plurality of types of voltages to the corresponding row decoder. Voltage boost circuitsgenerate a plurality of types of voltages by boosting a power supply voltage. A regulator circuitsteps down at least one of the plurality of types of voltages generated by the voltage boost circuitsto stabilize a voltage value, and outputs the resultant voltage to each switch. Each row decoderselects a memory cell by using a voltage outputted from the corresponding switch. Thus, it is possible to reduce a time required for a program/program verify operation, while reducing power consumption.
