Seymour Cray famously said "parity is for farmers" when asked why he left this out of the CDC 6600. Later, he included parity in the CDC 7600, which caused pundits to remark that "apparently a lot of farmers buy computers". The original IBM PC and all PCs until the early 1990s used parity checking. Later ones mostly did not. WebECC is disabled automatically if multiple programming operations are done on the same ECC unit. Single-byte programming or bit walking is allowed in certain flash device options, but it disables ECC on the second program to the same 16-byte ECC unit.

As raw BER in NAND flash increases to close to 10-2 at its life end, hard-decision ECC, such as BCH code, is not sufficient any more, and such more powerful soft-decision ECC as LDPC code becomes necessary. The outstanding performance of LDPC code is based on soft-decision information.
