Abstract
A system and technique for detecting and classifying data errors in a memory device. More specifically, data errors in a memory device are detected by a host controller. The error is classified as a hard error or a soft error. If the error is classified as a hard error, a tracking device is implemented to track the number of hard errors detected in the system. Once a pre-determined number of hard errors are detected in a particular memory segment, an indicator, such as a light emitting diode (LED), may be used to indicate the corresponding memory segment should be replaced.
