First Claim
Patent Images
1. A method for providing notification of a predictable memory failure, the method comprising:
- obtaining information regarding at least one condition associated with a memory;
calculating a memory failure probability as a function of the obtained information, the memory failure probability being defined as a probability of an occurrence of an uncorrectable error in the memory;
calculating a statistically-defined failure probability threshold as a function of at least one memory failure model and user-controllable notification settings, the at least one memory failure model being matched to at least one of a plurality of memory failure types;
generating a signal when the memory failure probability exceeds the failure threshold, the signal being indicative of a predicted future memory failure.

Abstract
A method for providing notification of a predictable memory failure includes the steps of: obtaining information regarding at least one condition associated with a memory; calculating a memory failure probability as a function of the obtained information; calculating a failure probability threshold; and generating a signal when the memory failure probability exceeds the failure probability threshold, the signal being indicative of a predicted future memory failure.
