Abstract
A method for storing in a nonvolatile memory by which a data restoration process is performed properly after a return from, for example, a shutoff of the supply of power. A storage management information store section in a central processing unit stores storage management information regarding the storage management of data to be stored in a nonvolatile memory by a data store section. The unit of the data is smaller than an erase unit in the nonvolatile memory. A storage completion information store section stores storage completion information indicative of the completion of the storing of the storage management information in the nonvolatile memory. A stored information judgment section judges, after a return from interruption of a process which occurred in the middle of the storage management information being stored, by referring to the storage completion information whether the storing of the storage management information is completed. Therefore, if the storing of storage management information is completed, a data restoration process can be performed properly by rewriting data.
