Abstract
A data storage device includes a nonvolatile memory device including a plurality of memory units; and a controller suitable for acquiring a temperature information for a current temperature, and for selectively adding a position information of a memory unit to a management list according to the temperature information.
Claims14
A data storage device comprising:
- a nonvolatile memory device including a plurality of memory units;
- and
- a controller suitable for acquiring temperature information for a current temperature when storing data in a memory unit, and for selectively adding position information of the memory unit to a management list when it is determined based on the temperature information that the current temperature is an abnormal temperature,
- wherein the management list includes position information of one or more memory units on which write operations are performed at the abnormal temperature, and
- wherein the controller reclaims the data stored in the memory unit corresponding to the position information included in the management list, when it is determined based on the temperature information that the current temperature is a normal temperature.

A method for operating a data storage device, comprising:
- acquiring temperature information for a current temperature when storing data in a memory unit;
- and
- selectively adding position information of the memory unit, to a management list when it is determined based on the temperature information that the current temperature is an abnormal temperature,
- wherein the management list includes position information of one or more memory units on which write operations are performed at the abnormal temperature, and
- wherein the data stored in the memory unit corresponding to the position information included in the management list is reclaimed when the current temperature is a normal temperature.
2 more elements
A data storage device comprising:
- a nonvolatile memory device;
- and
- a controller suitable for reclaiming data which is stored in the nonvolatile memory device at an abnormal temperature,
- wherein the controller waits instead of the reclaiming of the data when a current temperature is the abnormal temperature, and
- wherein the controller adds position information corresponding to the data, to a management list when storing the data in the nonvolatile memory device.
