In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.

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.

A power supply management circuit manages transfer of power that is supplied to a peripheral device from a power supply device. The power supply management circuit includes a current limiter and one or more capacitors. The current limiter limits intensity of first current received from the power supply device through an input terminal to be smaller than or equal to limitation intensity, and outputs second current having intensity limited to be smaller than or equal to the limitation intensity through an output terminal connected to the peripheral device. When the intensity of the first current exceeds the limitation intensity, the capacitors output third current through the output terminal.
