1. A non-volatile storage system, comprising:

  • a memory die including control circuitry and storage elements; and

    an external controller, external to the memory die and in communication with the control circuitry via at least one communication path, the external controller;

    maintains a record of multiple tasks for the control circuitry,provides a suspend command to the control circuitry via the at least one communication path while the control circuitry has the busy status, a first task executes at the control circuitry when the suspend command is provided;

    in response to detecting a ready status for the control circuitry;

    detects a suspend status of the control circuitry at a first time, updates the record based on the suspend status, and provides a second command to the control circuitry via the at least one communication path, andsubsequently, in response to again detecting the ready status for the control circuitry;

    detects the suspend status at a second time and if the suspend status at the second time is true, provides an additional command to the control circuitry via the at least one communication path.
