Abstract
An operating method of the soft-verify write assist circuit of the resistive memory provides a voltage level applying step, a write operating step and a write voltage controlling step. The voltage level applying step is for applying a plurality of voltage levels to the reference voltage, the word line and the switching signal, respectively. The write operating step is for driving the memory cell to perform in a set process or a reset process via the first three-terminal switching element, the second three-terminal switching element and the soft-verify controlling unit during a write operation. The write voltage controlling step is for controlling the write voltage to be increased in the ramping cycle and decreased in the soft-verify cycle.
