Abstract: Disclosed is a storage device which includes a nonvolatile memory device and a controller. The controller communicates with a host through a first port, communicates with an external storage device through a second port, and controls the nonvolatile memory device based on first mapping information. The controller is configured to receive second mapping information from the external storage device, receive first write data from the host and to selectively transmit first write data to the external storage device based on the second mapping information.

Abstract: A storage device includes a nonvolatile memory and a controller. The controller includes a job manager circuit and a processor. The job manager circuit manages a first-type job associated with the nonvolatile memory, and the processor processes a second-type job associated with the nonvolatile memory. The job manager circuit manages the first-type job without intervention of the processor. The processor provides a management command to the job manager circuit in response to a notification received from the job manager circuit, such that the second-type job is processed.
