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: An operation method is for a storage device that includes a storing unit storing a plurality of error logs and a physical layer and exchanges an electrical signal with a host via the physical layer. The operation method includes receiving a debugging command from the host, setting a first value at a first attribute included in the physical layer in response to the debugging command, setting a second value different from the first value at the first attribute in response to a control of the host, setting one among the plurality of error logs at a second attribute based on the first attribute at which the second value is set, and transmitting the error log set at the second attribute to the host in response to a control of the host.

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 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.
