Abstract
A data storage device includes a non-volatile memory, a temperature sensor, and temperature calibration circuitry coupled to the temperature sensor. The temperature calibration circuitry is configured to cause memory operations to be performed on storage elements of the non-volatile memory, to determine a temperature metric based on temperature readings from the temperature sensor in response to initiation of the memory operations, and to modify a temperature threshold based on the temperature metric.
Claims25
A data storage device comprising:
- a non-volatile memory;
- a temperature sensor;
- and
- temperature calibration circuitry coupled to the temperature sensor and
- configured to cause memory operations to be performed on storage elements of the non-volatile memory, to determine a temperature metric based on temperature readings that are generated by the temperature sensor in response to initiation of the memory operations, and to modify a temperature threshold based on the temperature metric.
A method of operation of a data storage device that includes a non-volatile memory and a temperature sensor, the data storage device storing an indication of a first temperature threshold associated with the data storage device, the method comprising:
- receiving temperature data from the temperature sensor;
- and
- in response to a temperature measurement associated with the data storage device satisfying a second temperature threshold, initiating a throttling mode of operation at the data storage device, wherein the second temperature threshold is based on the temperature data received from the temperature sensor.
An apparatus comprising:
- means for storing data;
- means for sensing a temperature associated with the means for storing data;
- and
- means for initiating memory operations at storage elements of the means for storing data, for determining a temperature metric based on temperature readings generated by the means for sensing in response to initiation of the memory operations, and for modifying a temperature threshold based on the temperature metric.
