RESISTIVE MEMORY APPARATUS AND WRITING METHOD THEREOF

摘要

A resistive memory apparatus and a writing method thereof are provided. In the method, logic data is received, and a corresponding resistive memory cell is selected. A logic level of the logic data is determined. When the logic data is in a first logic level, where a first reading current of the corresponding resistive memory cell is greater than a first reference current, a set pulse and a reset pulse are provided to the resistive memory cell during a writing period. When the logic data is in a second logic level, where a second reading current of the resistive memory cell is smaller than a second reference current, the reset pulse is provided to the resistive memory cell during the writing period. Polarities of the reset pulse and the set pulse are opposite.
