Temperature-based data refreshing

A data storage device comprising:

• non-volatile data storage media;
• means for determining temperature;
• means for generating heat within the data storage device;
• and
• a controller configured to:
• receive a write command from a host to write host data to the non-volatile data storage media;
• determine a temperature of at least a portion of the data storage device using the means for determining temperature;
• determine that the temperature of the at least a portion of the data storage device is below a first threshold;
• increase the temperature of the at least a portion of the data storage device using the means for generating heat;
• and
• when it is determined that the temperature of the at least a portion of the data storage device has risen above a second threshold, write the host data to the non-volatile data storage media.

A method for refreshing data in a data storage device, the method comprising:

• writing host data associated with a write command to non-volatile media of the data storage device while a temperature of at least a portion of a data storage device is at a first level below a first predetermined threshold;
• storing write indication data, the write indication data indicating that the data was written to the non-volatile media while the temperature of the at least a portion of the data storage device was below the first predetermined threshold;
• determining that the temperature of the at least a portion of the data storage device has risen to a second level that is above a second predetermined temperature threshold;
• and
• based at least in part on the determination that the temperature of the at least a portion of the data storage device has risen to the second level, re-writing the previously-written host data in the non-volatile media.
