Abstract
The invention relates to a method, a non-transitory computer-readable storage medium and an apparatus for accessing to encoding-history information. The method includes: providing a super-block formed by storage space of flash units, where the super-block includes zones, each zone includes super-page strings, and each super-page string includes pages across the flash units; and programming encoding-history information into a metadata section of a designated first page of a 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. The encoding-history information includes a history profile and history entries. The history profile indicates which zone or zones are covered in the super-block, and a quantity of the history entries. Each history entry includes 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.
