Patent ID: 8456943

Claim:
An electronic device being powered on when received a supply voltage from a power supply, the electronic device comprising: a memory storage device for storing data; a storing unit for receiving the supply voltage to store energy and releasing energy to generate a standby voltage when the power supply stops providing the supply voltage; and a voltage increasing unit for receiving the standby voltage, increasing the standby voltage, and providing the increased standby voltage to the memory storage device for preventing data loss in the memory storage device; wherein the storing unit comprises a first diode, a second diode, and a first capacitor; a cathode of the first diode is connected to the power supply and the comparing unit, an anode of the first diode is connected to a cathode of the second diode, an anode of the second diode is connected to the cathode of the first diode, an anode of the first capacitor is connected to the anode of the first diode, a cathode of the first capacitor is grounded.
