Zusammenfassung:PURPOSE: A semiconductor memory device and an operating method thereof are provided to reduce power consumption by preventing power from being supplied to latch circuits without data retention in a standby mode. CONSTITUTION: A page buffer(120) includes two or more latch circuits. A power terminal of one latch circuit is connected to an output terminal of a power supply unit. A power terminal of the other latch circuit is connected to a power line. A switching device is connected between the power line and the output terminal of the power supply unit and is turned on according to a standby mode signal. A control logic(150) generates a standby mode signal according to an operation mode.
