Methods and apparatus for thermal management in data storage devices are provided. One such data storage device includes a non-volatile memory (NVM), at least one ambient temperature sensor configured to detect an ambient temperature of the data storage device, at least one component temperature sensor configured to detect one or more component temperatures of one or more components of the data storage device, and a processor coupled to the NVM, the at least one ambient temperature sensor, and the at least one component temperature sensor. The processor is configured to determine a composite temperature of the data storage device based on the one or more component temperatures and the ambient temperature. The processor is further configured to determine whether the composite temperature exceeds a threshold and perform a thermal management operation if the composite temperature exceeds the threshold.

Management of composite cold temperature for data storage devices

A non-volatile storage device comprises non-volatile memory cells, clocked circuity, and one or more control circuits. The one or more control circuits are configured to process commands to access the non-volatile memory cells using the clocked circuity, implement a power control loop to regulate power consumption of the non-volatile storage device based on a first feedback signal, implement a temperature control loop to regulate temperature of the non-volatile storage device based on a second feedback signal, and implement a clock frequency control loop to regulate one or more clock frequencies of the clocked circuitry based on a third feedback signal.
