An electronic device connected to an external storage device and stores data transmitted from the storage device, the electronic device comprising a power supply, a control circuit and a storage unit. The power supply supplies a voltage to the storage unit via the control circuit. The control circuit generates a first control signal when the output voltage of the protection unit is less than a working voltage of the storage unit, and generates a second control signal when the output voltage of the protection unit is at least a working voltage of the storage unit. The storage unit is disabled in response to the first control signal, and enabled in response to the second control signal.
