Abstract
A memory system may include: a memory device including a memory cell array, the memory cell array including a plurality of scan areas, each of the plurality of the scan areas including at least two group areas, each of the group areas including a flag area storing a flag that represents whether a corresponding group area is programmed or not; and a controller suitable for requesting the memory device to read the flag of each of the group areas a flag when a sudden power-off occurs, and rebuilding at least one of the group areas when at least one of the flags is in an erase state.
