Abstract
An error correction code, especially suited for memory chips with multi-bit outputs, in which parity bits are calculated for each byte of the word and check bits are calculated for the word as a whole. In a 4-byte, 32-bit word, eight bits of error correction can correct up to four errors if the errors are restricted to corresponding bits in the 4 bytes.
