  • Publication number: 20260056831
    Abstract: A communication error between a memory sub-system controller and a memory device is detected. Based on the communication error being detected, execution of command processing by the memory sub-system controller is suspended. Command data comprising a snapshot of a command queue of the memory sub-system controller is stored. The command queue comprises one or more commands. The command queue is flushed. The memory sub-system is returned to a normal state of operation. One or more recovery actions are performed to attempt recovery of the memory device. Based on determining recovery of the memory device is unsuccessful, affected portions of the memory device are marked as retired. The one or more commands from the command queue are reissued.

  • Publication number: 20260038546
    Abstract: The disclosure configures a memory sub-system controller to enable debugging incomplete shutdown of a memory sub-system. The controller detects a power-loss event associated with incomplete shutdown of the memory sub-system. The controller, in response to detecting the power-loss event associated with the memory sub-system, retrieves a subset of debugging fields. The controller stores the subset of debugging fields in a reprogrammable read-only memory associated with the memory sub-system.
