Abstract
Provided are a method and apparatus for wear-leveling of a nonvolatile data storage device, whereby a wear-leveling effect is maximized by storing an age value indicating a write time in each data unit of the nonvolatile data storage device and detecting a static data area based on age values. The method includes storing an age value indicating a write time in each unit assigned to write data therein, reading an age value stored in a unit, and determining a static data area based on the read age value. Accordingly, a static data area can be correctly detected without additional overhead, and a wear-leveling effect of the entire storage device can be increased by moving data to and from the static data area, thereby extending the lifespan of the storage device.
