Command signal management methods and circuits in memory devices are disclosed. Command signals are selectively passed and blocked to enforce safe operating characteristics within a memory device. In at least one embodiment, a command signal management circuit is configured to selectively block a command signal while a memory device operation is being performed. In at least one other embodiment, one or more command blocking circuits are configured to selectively pass and block one or more command signals generated by a memory access device coupled to the memory device while a memory device operation is being performed in the memory device.
