摘要
A method of protecting data during transmission from an ECC protection scheme to a parity protection scheme, including reading a data word and an associated ECC from an upstream device; generating parity for the data word; generating a new ECC from the data word; computing a syndrome of the associated ECC and the new ECC; determining, based on the syndrome, if an error is present in the data word or the associated ECC; correcting a correctable error in the data word; correcting the parity for the data word; and transmitting the corrected data word and the corrected parity for the data word to a downstream device.
