Abstract
A storage device includes a nonvolatile memory device including memory blocks divided into a first memory area and a second memory area; and a memory controller. In the case of programming specific attribute data, the memory controller determines a memory area in which the specific attribute data will be programmed according to a wear out ratio of the first memory area and a wear out ratio of the second memory area. The wear out ratio is a ratio of the current maximum erase count of memory blocks of a memory area with respect to the allowable maximum erase count of the memory area.
