Methods of operating a memory, including receiving first data to be written to an array of memory cells of the memory, receiving error correction code (ECC) data corresponding to the first data, and receiving a flag having a value. Such methods further include storing the first data, the ECC data and the flag to the array of memory cells without performing error correction on the first data using the ECC data if the flag has a first value, and if the flag has a second value different than the first value and the first data does not contain an error. Such methods further include performing error correction on the first data using the ECC data, and storing corrected first data, the ECC data and the flag to the array of memory cells if the flag has the second value and the first data contains an error.
