Abstract
An error correction code for an array of N words of M bits each may be generated by: (i) for each word of the N words, computing a respective set of checkbits for single-error correction of such word; (ii) computing a set of bit-position-related checkbits comprising a bitwise logical exclusive OR of all of the sets of checkbits for single-error correction of the N words; (iii) for each word of the N words, computing a respective parity for the respective set of checkbits and the word itself in order to form a vector of N parity bits; (iv) computing a set of word-related checkbits for single-error correction of the vector of N parity bits; and (v) computing a cumulative parity bit comprising a parity calculation of the set of bit-position-related checkbits, the set of word-related checkbits, and the vector of N parity bits.
