Classification: CPC G | IPC G

Claim 9:
10. A memory device, comprising:
means for selecting a logical unit number (LUN) queue group, from which a command is to be transferred to an execution queue group, based on a most recently selected LUN queue group from which an immediately preceding command was transferred to the execution queue group,
wherein the selected LUN queue group and the most recently selected LUN queue group are included in a plurality of LUN queue groups associated with the memory device, and
wherein each LUN queue group, included in the plurality of LUN queue groups, is associated with a different LUN of a plurality of LUNs associated with the memory device;

means for selecting a LUN queue in the selected LUN queue group, from which the command is to be transferred to the execution queue group, based on a most recently selected LUN queue from which a most recently transferred command from the selected LUN queue group was transferred to the execution queue group,
wherein the selected LUN queue and the most recently selected LUN queue are included in a plurality of LUN queues that are included in the selected LUN queue group,
wherein each LUN queue, included in the plurality of LUN queues, is associated with:
an intra-LUN priority level used for selecting LUN queues within the LUN queue group, and
an execution priority level used for selecting commands from the execution queue group for execution,
wherein a quantity of intra-LUN priority levels associated with the selected LUN queue is greater than a quantity of execution priority levels associated with the execution queue group; and

means for transferring the command from the selected LUN queue to the execution queue group.
