15. A method of operating an apparatus including a memory array having one or more memory regions configured to store one or more codewords, the method comprising:
scanning, without outputting from the apparatus data strings corresponding to the one or more codewords, the one or more memory regions,
wherein scanning the one or more memory regions includes—
reading a first codeword from a first memory region of the one or more memory regions,
decoding the first codeword to reconstruct a first data string corresponding to the first codeword, and
determine a first bit error count (BEC) of the first codeword.
