Abstract
Reference nonvolatile memory groups in that data are easily erased during reading operation in comparison with a nonvolatile memory in a memory cell array is provided. Under control of a control circuit, data that is stored in the nonvolatile memory (7) is rewritten into the memory in accordance with the result of referring to the reference nonvolatile memory. Thus, the data characteristic of the memory is improved by rewriting data into the nonvolatile memory before a reading failure occurs.
