Hamming based block codes are the most commonly used ECC for SLC NAND. Hamming codes are relatively
straightforward and simple to be implemented in either software or hardware. The disadvantage of Hamming
codes is its limited error correction capabilities, with two bit errors detection and only one bit error correction.
Therefore, it is mainly used in SLC NAND flash applications.
Reed-Solomon and BCH are able to handle multiple errors. Both codes are powerful and able to handle both
random and burst errors. Reed-Solomon code is a subset of the BCH. However, BCH is simpler than Reed-
Solomon to decode and implement.

If so, I tested BCH and it was green.
