Abstract

A control method of a resistive random-access memory is provided. Firstly, an action is performed on the resistive random-access memory, so that the resistive random-access memory has a specified state. Then, an operation period begins. During a first sub-period of the operation period, a first control signal with a first polarity is provided. During a second sub-period of the operation period, a second control signal with a second polarity is provided. During a third sub-period of the operation period, a third control signal with the first polarity is provided. During a fourth sub-period of the operation period, a read signal is provided, so that the resistive random-access memory generates a read current. According to the read current, a controlling circuit verifies whether the resistive random-access memory is in the specified state.
