Abstract
A memory system comprises a memory device including plural memory blocks, and a controller coupled to the memory device. The controller controls the memory device to read a first group including plural data items and a parity associated with the plural data items from first locations in the plural memory blocks. The controller generates a new parity when the plural data items and the parity include plural errors, substitute one of the plural errors with the new parity and another of the plural errors with dummy data. The controller controls the memory device to program a second group including the new parity and the dummy data in second locations in the plural memory blocks. The second locations are different from the first locations.
