WebMay cause occasional errors in data access ! Reliability of memory can be improved by employing error-detecting and correcting codes ! Error-detecting code: only check for the existence of errors ! Most common scheme is the parity bit ! Error-correcting code: check the existence and locations of errors ! Web9 nov. 2024 · Detecting and correcting errors The best place to detect errors is during chip test. The weakest bits can be eliminated at that point. But even that is getting harder, given the number of bits and the increased communication channel challenges. That leaves the system to correct errors.
