• receiving first feedback information from one or more internal queues;
• controlling transfer of the data from the one or more submission queues to the one or more internal queues based on the first feedback information,
• receiving second feedback information from a memory device coupled to the processor, and
• controlling the transfer of the data from the one or more internal queues to the memory device based on the second feedback information.
