Thermal hardware-based data security device that permanently erases data by using local heat generation phenomenon and method thereof

Abstract

The present invention provides a thermal hardware-based data security device that is capable of physically, hardware-wise, and permanently erasing data stored in a memory and of enabling a storage device to be reused, and a method thereof. The thermal hardware-based data security device includes: a memory chip capable of storing data; a heater module which supplies heat to permanently erase the data stored in a memory cell within the memory chip; and a switch module which short-circuits the heater module between a power supply unit and a ground when switched on, and thus, controls the heater module to be operated.
