Abstract
A storage device may include: a memory device including a temperature sensor; and a memory controller for acquiring, from the memory device, temperature information sensed by the temperature sensor for a temperature management period, performing a performance limiting operation of limiting the performance of the memory device according to the temperature information, calculating the temperature management period by using the temperature information, and updating the temperature management period by using history information on a performance history of the performance limiting operation.
Claims18
A storage device comprising:
- a memory device including a temperature sensor;
- and
- a memory controller configured to:
- perform a temperature acquisition operation to acquire temperature information sensed by the temperature sensor during a temperature management period,
- calculate a minimum period and a maximum period based on the temperature information and a reference temperature management period, and
- update the temperature management period, using at least one selected from among the minimum period and the maximum period according to history information on a count of a performance limiting operation to limit an operating performance of the memory device, and
- perform the temperature acquisition operation according to the updated temperature management period.
A method for operating a storage device including a temperature sensor, the method comprising:
- performing a temperature acquisition operation to acquire temperature information sensed by the temperature sensor during a temperature management period;
- calculating a minimum period and a maximum period based on the temperature information and a reference temperature management period;
- updating the temperature management period using at least one selected from among the minimum period and the maximum period according to history information on a count of a performance limiting operation;
- and
- performing the temperature acquisition operation according to the updated temperature management period.
