Abstract
Methods and apparatus for management of thermal shutdown in data storage devices are provided. One such data storage device includes a non-volatile memory (NVM) including a thermal shutdown temperature indicative of a maximum temperature at which the NVM will retain data stored therein; and a processor coupled to the NVM, the processor configured to: determine whether a temperature at the NVM exceeds the thermal shutdown temperature; start, responsive to the determination that the temperature at the NVM exceeds the thermal shutdown temperature, a timer; determine, responsive to the timer reaching a preselected duration, whether the temperature at the NVM still exceeds the thermal shutdown temperature; cause, responsive to the determination that the temperature at the NVM still exceeds the thermal shutdown temperature, the NVM to be powered off; and maintain power to components of the data storage device other than the NVM.
