ABSTRACT:
A method for detecting logical addresses of a nonvolatile storage medium is proposed, which defines the nonvolatile storage medium into several zones each comprising a plurality of blocks. Only an address mapping table of the first zone or a commonly used zone is built and stored in a RAM so that the system can quickly obtain logical addresses in the nonvolatile storage medium. Therefore, the effects of quick access speed and no occupied memory space can be accomplished. Moreover, the cost can be effectively lowered, and the performance of data access of the system can be enhanced.
