Abstract
A storage device is provided which is capable of preventing characteristic degradation of the storage device at low temperature and reducing a failure. The storage device includes a memory device; a leakage current information storage for storing information associated with a leakage current generated based on a temperaturerange of the memory device; and a current controller for controlling the current internally consumed, based on the information associated with the leakage current, when a current temperature of the memory device is equal to or lower than a first temperature.
Claims18
A storage device comprising:
- a memory device;
- a leakage current information storage configured to store information associated with a leakage current generated based on a temperature range of the memory device;
- and
- a current controller configured to control a current internally consumed, based on the information associated with the leakage current, when a current temperature of the memory device is equal to or lower than a first temperature.
A method of operating a storage device including a memory controller and a memory device, the method comprising:
- measuring, by the memory controller, a temperature of the memory device;
- determining, by the memory controller, a leakage current margin range based on an amount of a leakage current for each temperature range of the memory device;
- and
- allowing, by the memory controller, a current to be internally consumed within the leakage current margin range.
A storage device comprising:
- a memory device;
- a current consuming component configured to generate heat by consuming a current;
- and
- a current controller configured to control the current flowing in the current consuming component until a current temperature of the memory device reaches a predetermined target temperature by the generated heat, when the current temperature is equal to or lower than a first temperature.
