An access interface is directed to read a group mapping table from the last page of a block of a storage unit. The block is allocated to store data of a plurality of groups, each group stores information indicating which location in the storage unit stores data of an LBA (Logical Block Address) range, and the group mapping table stores information indicating which unit of the block stores the latest data of each group. The group mapping table is stored in a DRAM (Dynamic Random Access Memory). The access interface is directed to read data of each group from the storage unit according to the group mapping table. The data of each group is stored in a specified location of a storage mapping table of the DRAM."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods for maintaining a storage mapping table and apparatuses using the same","description":"A method for maintaining a storage mapping table.
