    摘要: A storage device realizing an improvement in rewrite endurance of a nonvolatile memory and an improvement in data transfer rate of write and read operations is provided including a nonvolatile memory; a volatile memory for storing file management information of the nonvolatile memory; a controller for controlling the nonvolatile memory and the volatile memory; and a power supply maintaining unit for supplying power to the nonvolatile memory, the volatile memory, or the controller upon power shutdown. The controller reads the file management information in the nonvolatile memory upon power-on and writes the same in the volatile memory, and read and write operations are performed based on the file management information in the volatile memory, and the file management information in the volatile memory is written in the nonvolatile memory upon power shutdown.
