Storage device

Abstract

A storage device includes: a ferroelectric memory that temporarily stores data, wherein the ferroelectric memory stores an error correction code that is used for verifying the data by correcting errors possibly occurring on the data stored; a storage medium that has a plurality of storage regions and continually stores the data in one of the plurality of storage regions; and a control section that (1) writes the data and the error correction code to the ferroelectric memory, (2) writes the data written in the ferroelectric memory to one of the storage regions in the storage medium, (3) compares the data that is written in the ferroelectric memory and has been verified by using the error correction code written in the ferroelectric memory with the data written to the one of the storage regions in the storage medium, and (4) rewrites the data that has been verified to another one of the storage regions in the storage medium when both of the data do not match each other.
