Activating automatic sleep and wakeup sequences in a nand die based on another nand die status

Abstract

A die on a memory device enters a wakeup or sleep state based on statuses of other dies on the memory device. The die includes an input/output (IO) line to indicate its operation state. A processor on the die obtains a wakeup interrupt die number and a sleep interrupt die number set by a storage device connected to the memory device. The processor receives a broadcast command including IO statuses for IO lines associated with the other dies on the memory device. The processor determines when an IO line for a second die associated with the wakeup interrupt die number transitions from a 1 state to a 0 state and executes a wakeup sequence. The processor also determines when an IO line for a third die associated with the sleep interrupt die number transitions from the 0 state to the 1 state and executes a sleep sequence.
