Abstract

A method of error correction code (ECC) debugging for a system comprising, receiving data having an ECC, determining whether a data error has occurred, generating a syndrome of an error result, decoding flipped data bits, processing the received data and the decoded flipped bits to correct the data, outputting corrected data having an ECC, receiving a trap update signal, and saving the decoded flipped data bits responsive to receiving the trap update signal.
