Abstract:
A method of operating a memory controller controlling a nonvolatile memory device including a user area and a meta area is provided. The method includes selecting a source block among a plurality of memory blocks included in the user area, loading a mapping table stored in the meta area on the basis of a sub-bitmap of the selected source block, and generating a valid page layout constituted by valid pages among pages included in the source block on the basis of the loaded mapping table. The sub-bitmap includes information of a valid mapping table with respect to the selected source block.
