ABSTRACT:
On-line memory monitoring system and methods wherein memory subsystem performance is tracked to detect substandard performance and alert a system administrator of the nature of the substandard performance so corrective action can be taken before a system crash and/or automatic reset occurs. A computer system incorporating the invention includes a memory and a processor, wherein the memory storage includes data storage and error correction code storage for each dataword. The system further includes automatic error detection and correction circuitry and software which monitors the occurrence of correction of errors and compares their frequency with the known frequency of soft errors for the memory devices being used to determine whether an alert is to be given and the nature of any such alert.
