A controllable resistive element and method for updating the resistance of the same includes a state device configured to provide a voltage-controlled resistance responsive to a voltage input. A battery is configured to apply a voltage to the voltage input of the state device based on a charge stored in the battery. A write device is configured to charge the battery responsive to a write signal. An erase device is configured to discharge the battery responsive to an erase signal.

A method for updating the resistance of a controllable resistance element includes determining an amount of resistance change for the controllable resistive element. A charge difference for a battery is determined corresponding to the resistance change for the controllable resistive element. The battery is charged or discharged to effect the resistance change in the controllable resistive element.
