ABSTRACT:
A memory capable of preventing a memory cell from disappearance of data resulting from accumulated disturbances is obtained. This memory comprises a nonvolatile memory cell and a refresh portion for rewriting data in the memory cell. The refresh portion reads data from and rewrites data in the memory cell in a power-down state.
