Abstract
A storage device includes a memory, a controller, a first temperature sensor and a second temperature sensor. The storage device determines whether a preset weight reset condition is satisfied, based on at least one of the temperature of the memory measured from the first temperature sensor and the temperature of the controller measured from the second temperature sensor, and resets a weight for an increase in read count for data when it is determined that the weight reset condition is satisfied.
Claims20
A storage device comprising:
- a memory configured to store data;
- a controller configured to control the memory;
- a first temperature sensor configured to measure the temperature of the memory;
- and
- a second temperature sensor configured to measure the temperature of the controller,
- wherein the controller determines whether a preset weight reset condition is satisfied, based on at least one of the temperature of the memory and the temperature of the controller, and
- wherein, when it is determined that the weight reset condition is satisfied, the controller resets a weight for an increase in read count for the data.

A method for operating a storage device, the method comprising:
- obtaining the temperature of a memory from a first temperature sensor which measures the temperature of the memory in which data is stored;
- obtaining the temperature of a controller from a second temperature sensor which measures the temperature of the controller;
- is determining whether a preset weight reset condition is satisfied, based on at least one of the temperature of the memory and the temperature of the controller;
- and
- resetting a weight for an increase in read count for the data when it is determined that the weight reset condition is satisfied.
