Abstract
A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive a shutdown notification, fetch one or more command identifiers from a submission queue of a host device, generate error indications for the one or more command identifiers, and send a completion message, including the generated error indication, for each of the one or more command identifiers to the host device. The controller is further configured to push non-processed pending commands to a completion finite state machine, where the controller generates an error indication for each of the non-processed pending commands and sends a completion message, including the generated error indication, for each of the non-processed pending commands to the host device. While the controller is fetching command identifiers and pushing non-process commands, the controller is configured to continue processing processed commands in parallel.
