Abstract: A method of operating a memory device including a plurality of memory cells is provided. The method includes receiving a first write command, determining whether a target memory cell is deteriorated or not, in response to the first write command, and writing the second data by selectively erasing the target memory cell according to a result of the determination and by programming the target memory cell.

Abstract: A method of operating a memory controller includes classifying a plurality of memory cells in an erase state into a plurality of groups, based on erase state information about the plurality of memory cells in the erase state; setting at least one target program state for at least some memory cells from among memory cells included in at least one of the plurality of groups; and programming the at least some memory cells for which the at least one target program state has been set, to a program state other than the at least one target program state from among the plurality of program states.
