The set of M first codewords is produced such that at least one predetermined linear combination of the M first codewords produces a second codeword of the second BCH code, this second BCH code being a sub- code of the first BCH code.
The BCH code used is able to correct two errors.
A method for determining the locations of four errors in a code word of a Reed-Solomon or BCH code is disclosed.
A method for locating four errors in a codeword of a Reed-Solomon or BCH code is disclosed.
Input data words are encoded in groups of M input data words in accordance with first and second BCH codes to produce, for each group, a set of M first codewords of the first BCH code.
The most commonly used ECCs for flash memory are Bose-Chaudhuri-Hocquenghem (BCH) codes.
A label (100) for identification purposes, has a compact matrix of machine-readable cells (101-109) holding information and including the BCH error-correcting code.
