Abstract:
A memory device and controlling method for nonvolatile memory are provided. The memory device and the controlling method for a nonvolatile memory are provided by which, where a file management system wherein there is a tendency that lower logic addresses are used frequently like the MS-DOS is adopted, physical blocks of a flash memory are used in an averaged fashion and the life of the flash memory can be elongated thereby.
