Abstract
A storage device includes: a controller that exchanges data with a host through an interface; memory devices that store the data; a power supply circuit that outputs internal voltages, required for the controller and the memory devices, using an external voltage received through the interface; a distribution circuit that provides an operating voltage to the memory devices; and a discharge circuit including a first comparator that compares a first internal voltage, among the internal voltages, with a reference voltage and a second comparator that compares a second internal voltage, different from the first internal voltage, with the reference voltage, and including an operating circuit that computes an output of the first comparator and an output of the second comparator to output a discharge control signal determining whether the operating voltage has been discharged.
