A storage device is provided to store operation data of an electronic device when the electronic device experiences interruption of electric power . The storage device includes a processing module for storing the operation data, a switch module for outputting a charging voltage signal associated with a DC voltage signal, and an energy storage module charged by the charging voltage signal . The energy storage module outputs a determination voltage signal to the processing module in absence of the charging voltage signal . Further, the processing module converts the determination voltage signal into a digital value, and determines whether to read the operation data according to the digital value upon recovery of the electric power from the interruption. |
