  • Patent number: 12099743
    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. In one embodiment, the first level prediction is faster to make and uses less data collection, but is not as reliable, as the second level prediction. 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.

  • Patent number: 11687252
    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.

  • Patent number: 10015162
    Abstract: A method implemented by a network firewall, comprising obtaining a first authentication token for a network test, receiving a test request message for performing the network test on a network element (NE) connected to the network firewall, authenticating the test request message by determining whether the test request message includes a second authentication token that matches the first authentication token, and granting the network test on the NE when the second authentication token matches the first authentication token.
