Abstract
A resistive memory apparatus and an operating method thereof are provided. In the method, a set operation having a first enhanced bias is performed on at least one memory cell in a resistive memory array of the resistive memory apparatus, in which the first enhanced bias is larger than a bias used in a normal execution of the set operation. A heat process is performed on the memory cell. A set operation having a second enhanced bias is performed on the memory cell, in which the second enhanced bias is larger than or equal to the first enhanced bias.
