Zusammenfassung:An apparatus comprising a memory array including a plurality of memory cells arranged in a plurality of columns and a plurality of rows is provided. The apparatus further comprises circuitry configured to perform an error detection operation on the memory array to determine a raw count of detected errors, to compare the raw count of detected errors to a threshold value to determine an over-threshold amount, to scale the over-threshold amount according to a scaling algorithm to determine a scaled error count, and to store the scaled error count in a user-accessible storage location.
