Abstract:
1. A storage system, the storage system comprising: a first non-volatile memory portion and a second non-volatile memory portion, wherein the first non-volatile memory portion and the second non-volatile memory portion are addressable in the storage system; a failure indication circuit operable to identify the first non-volatile memory portion as read only upon determination that a subset of the first non-volatile memory portion is unreliable and the subset of the first non-volatile memory portion is larger than a threshold level; a time stamp circuit operable to identify a first point in time when the failure indication circuit identified the first non-volatile memory portion as read only; and an end of life circuit operable to estimate a second point in time based at least in part on the first point in time, wherein the second point in time corresponds to a time when the reliability of the storage system is unreliable.
