Abstract

Provided is a resetting method of a resistive random access memory (RRAM) including the following steps. A first resetting operation and a first verifying operation on the at least one resistive memory cell are performed. Whether to perform a second resetting operation according to a verifying result of the first verifying operation is determined. A second verifying operation is performed after the second resetting operation is determined to be performed and is finished. To determine whether to perform a healing resetting operation according to a verifying result of the second verifying operation, which comprises: performing the healing resetting operation when a verifying current of the second verifying operation is greater than a predetermined current, wherein a resetting voltage of the healing resetting operation is greater than a resetting voltage of the second resetting operation.
