Claim 6:
7. A non-transitory computer-readable storage medium for accessing to encoding-history information when executed by a processing unit, the non-transitory computer-readable storage medium comprising program code to:
provide a super-block formed by storage space of a plurality of flash units, wherein the super-block comprises a plurality of zones, each zone comprises a plurality of super-page strings, and each super-page string comprises a plurality of pages across the flash units; and
program the encoding-history information into a metadata section of a designated first page of a designated super-page string, wherein the encoding-history information comprises a history profile and a plurality of history entries, the history profile indicates which zone or zones are covered in the super-block, and a quantity of the history entries, and each history entry comprises information indicating that a designated second page of the designated super-page string in a designated zone hasn't been passed through an engine to generate a parity for the designated super-page string, thereby enabling a damaged page that is occurred in the designated super-page string of the designated zone to be recovered according to the encoding-history information.
