Abstract
An example device includes a memory device and one or more processors. The memory device is configured to store a table that includes two or more mappings, each mapping being associated with a respective logical address and a respective physical address. The processors are configured to identify, within the table, a first zone and a second zone. Each zone includes one or more mappings of the table. The zones do not share any mapping of the table. The processors are further configured to form a first log list indicating one or more mapping updates associated with the mapping(s) included in the first zone, to form a second log list indicating one or more mapping updates associated with the mapping(s) included in the second zone, and to replay a portion of the first log list and a portion of the second log list concurrently to update the table.
