Methods and apparatus for mitigating temperature increases in a solid state device (ssd)

A controller configured to manage a temperature of a data storage device, comprising:

• a temperature monitoring circuitry configured to monitor a temperature of one or more regions of the data storage device;
• a determiner circuitry configured to determine whether the temperature exceeds a threshold temperature;
• and
• an activation circuitry configured to:
• activate one or more thermoelectric cooler (TEC) devices to mitigate the temperature when the temperature exceeds the threshold temperature;
• and
• deactivate the one or more TEC devices that have been activated when the temperature no longer exceeds the threshold temperature.

A controller configured to manage a temperature of a data storage device, comprising:

• a processor configured to:
• monitor a temperature of one or more regions of the data storage device;
• determine whether the temperature exceeds at least one of a first threshold temperature or a second threshold temperature, wherein the second threshold temperature is greater than the first threshold temperature;
• and
• activate one or more thermoelectric cooler (TEC) devices when the temperature exceeds at least one of the first threshold temperature or the second threshold temperature, wherein the one or more TEC devices are activated using a first TEC activation configuration when the temperature exceeds the first threshold temperature, and wherein the one or more TEC devices are activated using a second TEC activation configuration when the temperature exceeds the second threshold temperature.

An apparatus configured to manage a temperature of a data storage device, comprising:

• means for monitoring a temperature of one or more regions of the data storage device;
• means for determining whether the temperature exceeds a threshold temperature;
• means for mitigating the temperature based on thermoelectric cooling;
• and
• means for activating the means for mitigating the temperature when the temperature exceeds a threshold temperature.

A method of operating a controller to manage a temperature of a data storage device, comprising:

• receiving a command for a memory operation;
• analyzing the command to determine whether execution of the command with thermal throttling would have a negative impact on a user experience;
• and
• activating, if execution of the command with the thermal throttling would have the negative impact on the user experience, one or more thermoelectric cooler (TEC) devices while refraining from performing the thermal throttling.

A method of operating a controller to manage a temperature of a data storage device, comprising:

• receiving a command for a memory operation;
• determining a memory operation workload of the controller;
• activating one or more thermoelectric cooler (TEC) devices when the memory operation workload of the controller exceeds at least one of a first workload threshold or a second workload threshold, wherein the second workload threshold is greater than the first workload threshold;
• and
• executing the command, wherein the command is executed while refraining from performing thermal throttling when the memory operation workload exceeds the first workload threshold, and wherein the command is executed with the thermal throttling when the memory operation workload exceeds the second workload threshold.
