Zusammenfassung:A control method for a non-volatile memory is provided. After the non-volatile memory is enabled, a judging step is performed to judge whether the non-volatile memory enters a read mode, a program mode or an erase mode. If the judging result indicates that the non-volatile memory enters the read mode, the program mode or the erase mode, a worst threshold voltage of plural reference cells of the non-volatile memory is searched. Then, at least one of a control voltage for read action, a control voltage for program verify and a control voltage for erase verify is determined. Then, a read action, a program action or an erase action is performed on plural data cells of the non-volatile memory.
