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 descramble module configured to descramble at least a portion of a read command, which includes logical block address (LBA) information and first meta information, into first signature information and first physical address (PA) information, for accessing a flash memory. A compare module is provided, which is configured to compare the first signature information against stored signature information to thereby determine an equivalency or discrepancy therebetween. An access module is provided, which is configured to use the first PA information to access a data region of the flash memory, upon determination of the equivalency by said compare module.

Abstract: Provided is a storage device which communicates with a host device and configured to set a secure mode of a plurality of commands different in kind. An operating method of the storage device includes receiving a secure request indicating a protection of a first command and a protection of a second command of the plurality of commands, from the host device; setting a secure mode of the first and second commands, based on the secure request; receiving a first request indicating a request to execute the first command, from the host device; outputting a first response indicating failure of the first command to the host device, based on the first request; receiving a second request indicating a request to execute the second command, from the host device; and outputting a second response indicating failure of the second command to the host device, based on the second request.

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 storage device including: a nonvolatile memory device including a first, second and third area; and a controller to receive a first write command including a first logical block address from a host, to receive first data corresponding to the first logical block address in response to the first write command, and store the first data in the nonvolatile memory device, when the first write command includes area information, the controller stores the first data in the first area or the second area based on the area information, when the first write command does not include the area information, the controller stores the first data in the third area, each of the first area and the second area includes memory cells each storing “n” bits (n being a positive integer), and the third area includes memory cells each storing “m” bits (m being a positive integer greater than n).
