Abstract: A solid state drive (SSD) storage system includes a memory controller, host interface, memory channels and solid state memories as storage elements. The completion status of sub-commands of individual read commands is monitored and used to determine an optimal selection for returning data for individual read commands. The completion of a read command may be dependent on the completion of multiple individual memory accesses at various times. The queueing of multiple read commands which may proceed in parallel or out of order causes interleaving of multiple memory accesses from different commands to individual memories. A system and method is disclosed which enables the selection, firstly of completed read commands, independent of the order they were queued and, secondly, of partially completed read commands which are most likely to complete with the least interruption or delay, for data transfer, which in turn improves the efficiency of the data transfer interface.
