1. A method of error detection and correction of a data transmission, the method comprising: receiving a block of data, the block of data comprising a predefined number of words, each word including a parity bit, the block of data further comprising an error-correcting code (ECC), the ECC included in the block of data further comprises a sum of all words of the block excluding parity bits prior to transmission of the data; determining, for each word in dependence upon the parity bit of the word, whether the word includes a parity error; committing the word if the word does not include a parity error; and if only one word of the block includes a parity error: correcting the one word that includes the parity error through use of the ECC of the block and committing the corrected word, wherein correcting the word that includes the parity error includes: calculating a verification ECC as a sum of all words of the received block excluding parity bits; calculating a difference between the verification ECC and the ECC included in the block of data; and adding the difference to the single word that includes the parity error.
2. The method of claim 1 further comprising: if more than one word includes a parity error, discarding all words that include a parity error.
