Abstract: A method for operating a memory includes determining to perform an error correction operation; determining whether to perform an error correction operation; generating an internal address when the error correction operation is performed; reading data from memory cells that are selected based on the internal address and an error correction code corresponding to the data; performing an error correction operation on the data based on the error correction code to produce an error-corrected data; writing the error-corrected data and an error correction code corresponding to the error-corrected data into the memory cells; determining one or more regions among regions in the memory as a repair-requiring region based on an error detected when the error correction operation is performed; receiving a first command; backing up the data and the error correction code into a redundant region in response to the first command; and repairing the repair-requiring region with the redundant region.
