Abstract
A power gating device may include a control unit that generates a first interrupt signal based on a mode change signal when a mode of a system is changed from a normal operation mode to a stand-by mode, and generates a second interrupt signal based on the mode change signal when the mode is changed from the stand-by mode to the normal operation mode, a memory unit that stores data of a function block based on the first interrupt signal, and restores the stored data to the function block based on the second interrupt signal, and a power source unit that provides a normal operation power to the function block and the memory unit based on a power down signal in the normal operation mode, and provides a stand-by power to the memory unit based on the power down signal in the stand-by mode.
