Abstract: A storage device includes: a storage controller to receive one or more notifications corresponding to host data transferred from a host device to the storage device over a storage interface; and a response circuit connected to the storage controller, the response circuit to trigger a response to the host device, and including: a first counter to track the one or more notifications, the one or more notifications corresponding to an entirety of the host data such that each of the notifications corresponds to a portion of the host data; a second counter to track one or more acknowledgements received from the storage controller, the one or more acknowledgments corresponding to the one or more notifications such that each of the acknowledgments corresponds to a notification; and a response trigger to select one of the first counter and the second counter to trigger the response to the host device.

Abstract: A storage device includes: a host interface to receive a host command from a host device over a storage interface; one or more memory translation layers to execute one or more operations associated with the host command to retrieve one or more chunks of data associated with the host command from storage memory; a bitmap circuit including a bitmap to track a constrained order of the one or more chunks of data to be transferred to the host device; and a transfer trigger to trigger a data transfer to the host device for the one or more chunks of data in the constrained order according to a state of one or more bits of the bitmap.
