摘要：
A data storage device comprises a plurality of non-volatile memory devices configured to store a plurality of physical pages; a controller coupled to the plurality of memory devices that is configured to program data to and read data from the plurality of memory devices. A volatile memory may be coupled to the controller and may be configured to store a firmware table comprising a plurality of firmware table entries. The controller may be configured to maintain a plurality of firmware journals in the non-volatile memory devices. Each of the firmware journals may be associated with a firmware table entry and may comprise firmware table entry information. The controller may be configured to read the plurality of firmware journals upon startup and rebuild the firmware table using the firmware table entry information in each of the read plurality of firmware journals.
