ABSTRACT:
A semiconductor memory device includes a boosting power supply circuit that boosts a first voltage to a second voltage, which is higher than an external power supply. A first bandgap reference (BGR) circuit operates on the second voltage generated by the boosting power supply circuit. Thereby, the power supply circuit generates a voltage by using a bandgap reference circuit.
