A first objective is to reduce performance degradation of a semiconductor storage resulting from address translation. A second objective is to reduce an increase in the manufacturing cost of the semiconductor storage resulting from address translation. A third objective is to provide the semiconductor storage with high reliability. To accomplish the above objectives, a storage area of a nonvolatile memory included in the semiconductor storage is segmented into multiple blocks, and each of the blocks is segmented into multiple pages. Then, an erase count is controlled on a page basis (109), and address translation is controlled on a block basis (108). |
