Abstract
A method for tracking errors in a memory system by detecting an error in a bit of a word accessed in the memory and maintaining an error history comprising a record of each of the detected errors. The error history information may be used to configure the memory, such as to add redundancy; or may be used to adjust operating parameters of the memory, such as the periodicity of refresh and/or scrub operations; or may be used to trigger a sensing operation of other parameters in an application system. In one embodiment, a counter increments each time an error is detected and decrements when no error is detected, thereby tracking error patterns.
