    摘要: An apparatus includes a cache memory for storing user data and control information of the apparatus, a nonvolatile memory and a processor for executing a process including when the power failure occurs, saving the user data and the control information stored in the cache memory into the nonvolatile memory, when the power failure recovers, restoring the data stored in the nonvolatile memory into the cache memory, and erasing the data stored in the nonvolatile memory after restoring the data into the cache memory and when another power failure occurs during erasing the data stored in the nonvolatile memory, erasing the control information stored in the nonvolatile memory if the control information is remained in the nonvolatile memory and saving, into the nonvolatile memory, the updated control information stored in the cache memory and the user data which has been erased from the nonvolatile memory.
