Abstract

A copy-back method of a storage device includes reading a memory data from a source area of the storage device. A number of error bits of the memory data is determined. An inspection read operation is performed if the number of error bits exceeds a reference value. The memory data is written to a destination area of the storage device if the number of error bits does not exceed the reference value.
