Claim Text:
1. A repairing method of a resistive memory, comprising: operating a plurality of set-reset cycles on the resistive memory, each of the set-reset cycles comprising a set programming and a reset programming, wherein a set voltage is applied on the resistive memory during a set time period to execute the set programming, and a reset voltage is applied on the resistive memory during a reset time period to execute the reset programming; detecting whether the resistive memory encounters an over-set issue after operating the set-reset cycles; and if the resistive memory encounters the over-set issue, executing an enhanced reset programming on the resistive memory, wherein the enhanced reset programming is executed by applying an enhanced reset voltage on the resistive memory during an enhanced reset time period, and a product of the enhanced reset time period and the enhanced reset voltage is larger than a product of the reset time period and the reset voltage.
