CONTROLLING METHOD FOR SOLID STATE DRIVE WITH RESISTIVE RANDOM-ACCESS MEMORY

摘要

A controlling method for a solid state drive is provided. The solid state drive includes a controlling circuit and a resistive random-access memory. Firstly, a monitor factor is defined. The monitor factor is associated with a life span of the resistive random-access memory. If the monitor factor is higher than a predetermined value, a mapping algorithm of a logical-to-physical table is established by the controlling circuit and a logical block address of a host is mapped to a physical allocation address by the controlling circuit according to the logical-to-physical table, and a data accessing action is performed.
