Abstract: A storage device that includes a nonvolatile memory device is described. The storage device includes areas and a controller. The controller receives a write command and data from an external host device. The controller then preferentially writes the data in an area associated with a turbo write based on a turbo write policy, or in an area not associated with a turbo write based on a normal write policy. The controller also receives a move command from the external host device and moves data stored in the area to a different area based on the move command.

Abstract: A method of operating a storage device includes receiving, at the storage device, a meta information transfer command based on a data read request. The meta information transfer command is received from a host device. The method further includes receiving, at the storage device, a data read command corresponding to the data read request and the meta information transfer command. The data read command is received from the host device. The method further includes receiving, at the storage device, a plurality of meta data corresponding to the data read request and the meta information transfer command. The plurality of meta data is received from the host device. The method further includes performing a data read operation, at the storage device, based on the data read command and the plurality of meta data.

Abstract: A storage device includes a nonvolatile memory device that includes a first region including memory cells configured to store n-bit data and a second region including memory cells configured to store m-bit data and a memory controller, where n and m are natural numbers and n is less than m. The first region includes a first area and a second area, and the second region includes a third area. The memory controller is configured to perform one of a turbo write operation on the first area or the second area and a normal write operation on the third area, and configured to perform one of a turbo read operation on the first area or the second area and a normal read operation on the third area.

Abstract: A storage device includes a nonvolatile memory device including a first region and a second region, and a controller that receives a first operation command including move attribute information and a first logical block address from an external host device and moves first data corresponding from the first region to the second region in response to the received first operation command, and when the first operation command does not include the move attribute information, the controller performs a first operation corresponding to the first operation command.

Abstract: A storage device includes a nonvolatile memory device that includes a first area, a second area, and a third area, and a controller that receives a write command and first data from a host device, preferentially writes the first data in the first area or the second area rather than the third area when the first data is associated with a turbo write, and writes the first data in the first area, the second area, or the third area when the first data is associated with a normal write. The controller moves second data between the first area, the second area, and the third area based on the policy received from the host device.

Abstract: A storage device including a nonvolatile memory device is described. The storage device includes a controller that receives a write command and data from an external host device. The controller preferentially writes the data in an area based on a normal write policy when the data is associated with a normal write, and in an area based on a turbo write policy when the data is associated with a turbo write. The controller may also receive a read command, to read data from an area based on the read command, and output the data to the external host device. The controller may also move the data in response to move information of the read command when the read command is received together with move information.

Abstract: An operating method of a storage device that includes a nonvolatile memory device and a controller configured to control the nonvolatile memory device includes sending map data from the storage device to a host device, the map data mapping one or more of a plurality of physical addresses of the nonvolatile memory device to one or more of a plurality of logical addresses of the host device; receiving, at the storage device, a read request from the host device; if the read request includes a physical address, reading data from the nonvolatile memory device based on the included physical address; and if the read request does not include a physical address, translating a logical address of the read request into a first physical address, and reading data from the nonvolatile memory device based on the translated first physical address.
