Abstract: A storage device includes an accelerator including a first processor, and a storage controller that uses a buffer memory as a working memory and includes a second processor different in type from the first processor. The second processor is configured to establish a first communication path between the first processor and the buffer memory responsive to a request of the first processor, and the first processor is configured to access the buffer memory through the first communication path.

Abstract: A storage device includes a memory device and a controller. The controller includes a programmable logic device which is reconfigurable, based on requests which are received from an outside of the storage device, to adaptively support a plurality of protocols depending on the requests. As the programmable logic device is programmed to support a first protocol among the plurality of protocols based on a first request which is received from the outside of the storage device with regard to the first protocol, the programmable logic device processes the first request in compliance with the first protocol, and the controller communicates with the memory device based on the first request such that the memory device stores or outputs data corresponding to the first request.

Abstract: A storage device is provided. The storage device is connected to a debugging host and includes a nonvolatile memory device; a storage controller configured to control the nonvolatile memory device; and a secure debugging manager configured to count a number of times that a password input from the debugging host and a registered password are mismatched and to block access of the debugging host based on the number of times reaching a threshold count, the storage controller being further configured to store the number of times in the nonvolatile memory device and provide the number of times to the secure debugging manager.
