1. A host device, comprising:
- a driver that is arranged and configured to communicate commands to a data storage device; and
multiple pairs of queues, wherein each of the pairs of queues comprises;
a command queue that is populated with commands for retrieval by the data storage device, anda response queue that is populated with responses by the data storage device for retrieval by the host device, wherein each response queue is associated with an interrupt and an interrupt handler.

10. A method for communicating commands between a host and a data storage device, the method comprising:
-
using multiple different threads to communicate commands to a data storage device; using multiple pairs of queues, wherein each pair of queues includes a command queue, a response queue, an interrupt and an interrupt handler; and associating each pair of the queues with one or more of the threads, wherein using the pairs of queues comprises; populating the command queue with commands for retrieval by the data storage device, and populating the response queue with responses by the data storage device for retrieval by a host device. - View Dependent Claims (11, 12, 13)

14. A system comprising:
-
a data storage device including a plurality of memory chips and multiple physical channels for communication of data between a host and the plurality of memory chips, each channel being operably connected to a different plurality of the memory chips; and a host operably coupled to the data storage device using an interface, the host comprising; a driver that is arranged and configured to communicate commands to the data storage device; and multiple pairs of queues, wherein each of the pairs of queues comprises; a command queue that is populated with commands for retrieval by the data storage device, and a response queue that is populated with responses by the data storage device for retrieval by the host device, wherein each response queue is associated with an interrupt and an interrupt handler. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
