Abstract: Disclosed is a storage device, which includes a nonvolatile memory device, and a controller that controls the nonvolatile memory device. In response to a first command, a barrier command, and a second command being received from an external host device, the controller supports an order guarantee between the first command and the second command. Each of the first command and the second command is selected from two or more different commands. In response to a request from the external host device, the controller circuitry is configured to provide the external host device with a device descriptor associated with the ordering.

Abstract: A memory system includes a storage device including a turbo write buffer and a user storage area implemented with a nonvolatile memory, and a host configured to transfer a read request to the storage device. In response to the read request, the storage device transfers read data and read data information including attributes of the read data to the host.

Abstract: A storage system includes a host device supporting multiple queues and a storage device communicating with the host device. The host device may include first and second cores, first and second queues corresponding to the first and second cores and storing commands, and a host controller that sets a queue ID and/or a parallelism demand level for each commands stored in the first and second queues. The storage device may include nonvolatile memories and a storage controller that detects pattern information of commands, received from the host device, based on the queue ID and places the commands, received from the host device, in the nonvolatile memories based on the pattern information.

Abstract: A storage device may include a non-volatile memory configured to store one file as a plurality of file fragments, and a storage controller configured to receive a read command with respect to the plurality of file fragments from a host through UFS protocol information unit (UPIU), and perform prefetching on the plurality of file fragments based on file fragmentation information included in an extra header segment (EHS) field of the UPIU.
