Abstract:
Aspects of the disclosure provide for reducing a temperature of one or more non-volatile memory (NVM) dies of a solid state drive (SSD). The methods and apparatus detect a temperature of one or more NVM dies of a plurality of NVM dies of the SSD, the plurality of NVM dies including at least one parity NVM die, and determine that the one or more NVM dies is overheated when the detected temperature is at or above a threshold temperature. If the detected temperature is at or above the threshold temperature, the methods and apparatus redirect parity data designated for the at least one parity NVM die to the one or more overheated NVM dies. By repurposing the one more overheated NVM dies to store the parity data, the repurposed dies will experience less activity, and therefore, generate less heat without throttling or reducing the workload capability of the dies.
