Abstract
Garbage collection technology for non-volatile memory is shown. Space allocation of the non-volatile memory is presented by a plurality of logical-to-physical address mapping sub-tables. The processor selects a plurality of source blocks and a destination block from the non-volatile memory for garbage collection. In order from the lowest to the highest logical address, the processor selects the logical-to-physical address mapping sub-tables in turn for use as a scan target, to perform a full scan of each logical-to-physical address mapping sub-table. In this way it identifies valid data in the source blocks, collects the valid data obtained from the source blocks, and programs the valid data to the destination block.
