Abstract

Command scheduling for die sets of non-volatile memory may be performed based on command states of the die sets. Upon receiving an erase command to erase data stored in a first block set of non-volatile memory, a command state of the first die set of the non-volatile memory is determined, where the first die set contains the first block set. If the first die set is determined to be in a pending command state, the erase command is queued in a wait queue. If the first die set is determined to be in an idle command state, the erase command is scheduled to erase the data stored in the first block set.
