Abstract
A maintaining device and a maintenance method for maintaining the normal operation of a resistive random access memory are disclosed. The maintenance method can be executed by the maintaining device. Said memory includes first and second electrodes. The first electrode is not grounded. The maintaining device is connected to the first electrode so that the first electrode receives an operational signal and a restoring signal generated by the maintaining device. The operational signal transits from a zero voltage to a non-zero voltage and then to the zero voltage. If the operational signal has already transited from the non-zero voltage to the zero voltage, the maintenance method controls the restoring signal to transit from the zero voltage to a negative voltage, controls the restoring signal to remain the negative voltage for a period of restoring time, and controls the restoring signal to transit from the negative voltage to the zero voltage.
