Abstract: A non-volatile storage apparatus comprises a plurality of memory cells that store host data and two models, a control circuit for writing to and reading from the memory cells, and an inference circuit. The inference circuit uses the first model with a first set of one or more metrics describing current operation of the non-volatile storage apparatus to make a first level prediction about defects and uses the second model with a second set of one or more metrics describing current operation of the non-volatile storage apparatus to make a second level prediction about defects.

While second level prediction is more reliable, it takes more time to perform and requires a more intensive data collection, so it is only used when needed.
