Predictive memory maintenance in accordance with one aspect of the present description, can anticipate a failure of a selected primary memory die of an array, and pre-load a spare memory die with the data of the selected primary memory die deemed to have a likelihood of failure, prior to any actual failure of the selected memory die. In the event that the selected primary memory die does subsequently fail, the spare memory die pre-loaded with the data of the selected primary memory die can readily take the place of the failed primary memory die with a pre-existing copy of the data of the failed primary memory die. Other aspects are described herein.
