Claim:
1. A storage device, comprising: a first power supply unit and at least one first storage cell, wherein the at least one first storage cell stores first data which are associated with a number of charges within the first storage cell, wherein the first power supply unit is electrically connected to the at least one first storage cell, and a first control unit configured for controlling the first power supply unit to supply power to the at least one first storage cell according to a predetermined policy, so that the number of charges within the first storage cell satisfies a first preset condition, wherein the first control unit is further configured: for determining whether a voltage corresponding to the charges in the first storage cell is lower than a first threshold; and for controlling the first power supply unit to supply power to the first storage cell so that the voltage corresponding to the charges representing the first data is higher than the first threshold, when the voltage corresponding to the charges in the first storage cell is lower than the first threshold.
