Abstract
A memory system includes a plurality of memory devices, a buffer memory, and a controller. The controller generates bitmap information for a plurality of pages to distinguish a first page on which a read operation has succeeded from a second page on which the read operation has failed, and stores the bitmap information in the buffer memory, whenever completing the read operation for each of the plurality of pages. The controller generates parity data by cumulatively performing a parity operation on data of the first page whenever performing the read operation on each of the plurality of pages, and stores the parity data in the buffer memory. The controller checks the bitmap information after the read operations on the plurality of pages are completed, and recovers data of the second page by referring to the parity data when the second page is present among the plurality of pages.
