After a total number of logical blocks, which exceeds a specified number, have been programmed into a storage unit, an access interface is directed to program a corresponding group of a storage mapping table of a DRAM (Dynamic Random Access Memory) into a first block of the storage unit according to a group number of an unsaved group queue. A group mapping table of the DRAM is updated to indicate that the latest data of the group of the storage mapping table is stored in which location in the storage unit. The group number is removed from the unsaved group queue."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for flash memory storage mapping table maintenance via DRAM transfer","description":"The method for maintaining a storage mapping table is introduced.
