Abstract
Disclosed herein are related to a controller, a method, and a system for updating mapping information between a logical address and a physical address of a corresponding region of a memory device. In one aspect, the controller generates a plurality of entries, where each entry indicates an update in the mapping information associated with the corresponding region. The controller generates a plurality of headers, where each header is associated with one or more entries in the corresponding region. The controller receives an instruction to synchronize the mapping information stored on the memory device with the update in the mapping information. The controller generates a copy of the plurality of headers in response to receiving the instruction to synchronize. The controller synchronizes the mapping information stored on the memory device according to the copy of the plurality of headers and the plurality of entries.
