Abstract: A storage device which includes a nonvolatile memory device that includes a memory circuit storing first device information and that operates based on the first device information, a storage controller that controls the nonvolatile memory device, and a buffer memory that stores map data managed by the storage controller and stores second device information being a backup of the first device information. The first device information includes information about an operation parameter and an operation frequency of the nonvolatile memory device. The storage controller further performs a recovery operation on the first device information stored in the memory circuit of the nonvolatile memory device, based on the second device information stored in the buffer memory.
