Abstract:
A method for accessing data in a circular block mode, executed by a processing unit, is introduced to contain the following steps. A read command and an LBA (Logical Block Address) are obtained from a host device through a first access interface. Logical block and page numbers are calculated according to the LBA, and a record associated with the logical block number is read from a storage mapping table, where the record contains a physical block number and a circular index. A physical page number is calculated according to the logical page number and the circular index. A read command is issued to a storage unit through a second access interface for reading data of the LBA from a region associated with the physical block number and the physical page number, and the data is replied to the host device through the first access interface.
