Abstract
A flash memory device. The flash memory device comprises a controller, a plurality of flash memories, and a voltage control circuit. The voltage control circuit comprises a boost converter, a buck converter, and a voltage controller. The boost converter receives a system voltage to generate a first high voltage. The buck converter receives the first high voltage and provides an output voltage to the controller and the flash memories. The voltage controller detects the output voltage generated by the buck converter, and therefore generates a feedback signal. When the voltage controller receives a physical destruction control signal from a host computer, the buck converter will generate an output signal with high level according to the control of the feedback signal. Afterwards, semiconductor physical elements of the controller and the flash memories will be burned by the output signal with high level.
