Bad data bits identified during error correction code (ECC) correction of runtime memory access fails or during background scrub (soft error cleanup) can be used to correct a fail rather than just ending system processing. The identified bad bit(s) can also be used to improve field replaceable unit (FRU) callouts. This process/device can be used to correct fails on any interface where failing data bits can be identified and logged.
