Abstract
A non-volatile storage apparatus comprises one or more memory die assemblies, each of which includes an inference circuit positioned in the memory die assembly. The inference circuit is configured to use a pre-trained model (received pre-trained from a source external to the non-volatile storage apparatus and stored in a dedicated block in non-volatile memory) with one or more metrics describing current operation of the non-volatile storage apparatus in order to predict a defect in the non-volatile storage apparatus and perform a countermeasure to preserve host data prior to a non-recoverable failure in the non-volatile storage apparatus due to the defect.
