A semiconductor memory device includes memory cells, a memory cell array, word lines, a first charge pump circuit, and a discharge circuit. The memory cell has a first MOS transistor with a stacked gate including a floating gate and a control gate. The memory cell array includes the memory cells arranged in a matrix. The word line connects commonly the control gates of the first MOS transistors in a same row. The first charge pump circuit is activated and generates a first voltage in a write operation and erase operation. The first voltage is supplied with either the well region or the word lines. The discharge circuit, when the first charge pump circuit is deactivated, discharges the charge generated by the first charge pump circuit to ground or to a power-supply potential, while causing current to flow to an output node of the first voltage.

A voltage stepup circuit having a plurality of setup circuit units connected in stages between an input voltage node and a stepup voltage node. Each circuit unit comprises at least two first and second MOS transistor T1 and T2. Each of first stepup capacitors is connected between a first clock signal supply node and a first connection node at which the drain and gate of a corresponding one of odd-numbered MOS transistors, of a plurality of MOS transistors connected in series through the plurality of stepup circuit units, are connected together. Each of second stepup capacitors is connected between a second connection node at which the drain and gate of a corresponding one of even-numbered MOS transistors of the plurality of MOS transistors connected together and a second clock signal supply node for supplying said second connection node with a second clock signal whose pulse width does not overlap in time with that of the first clock signal. A first clock amplitude control circuit limits the amplitude of the first clock signal to be supplied to the first clock signal supply node to a predetermined level and applies the first amplitude-limited clock signal to the first clock signal supply node. A second clock amplitude control circuit limits the amplitude of the second clock signal to be supplied to the second clock signal supply node to a predetermined level and applies the second amplitude-limited clock signal to the second clock signal supply node.

An oscillator including a CMOS inverter, a feedback reactance connected between the input and output terminals of the CMOS inverter and a CMOS transfer gate connected as a feedback resistor between the input and output terminals of the CMOS inverter, a power source terminal section to which an external voltage is applied, and a power control unit for converting the external voltage to a first internal voltage which is supplied as a power source voltage to the CMOS inverter. The power control unit converts the external voltage to a second internal voltage independently from the first internal voltage and supplies the second internal voltage as a gate control voltage to the CMOS transfer gate.
