STORAGE DEVICES AND METHODS OF DRIVING STORAGE DEVICES

摘要

A storage device includes a data storage having first and second storage areas corresponding to different physical addresses. First data are stored in the first storage area. The storage device further includes a first memory that stores a reference count associated with the first data, and a controller that rearranges the first data from the first storage area to the second storage area in response to a change in the reference count of the first data.
