A memory device may receive a set of commands from a host device. The memory device may determine whether the set of commands are associated with a shutdown procedure based on a pattern of the received set of commands. The memory device may initiate one or more operations associated with the shutdown procedure based on identifying that the set of commands are associated with the shutdown procedure. The memory device may receive a shutdown command for the shutdown procedure after initiating the one or more operations associated with the shutdown procedure. The memory device may determine that the set of commands are associated with the shutdown procedure based on a quantity of the set of commands, one or more types of the set of commands, other thresholds associated with the pattern, or a combination thereof. ## Claims ### Claim 1 A memory system, comprising: one or more memory devices;
