Claim 16:
17. A data storage device, comprising:
a non-volatile memory device including a plurality of memory dies, wherein each of the plurality of memory dies include a temperature sensor configured to monitor a temperature; and
a controller configured to:
poll each of the plurality of memory dies at a first predetermined rate for a thermal status bit;
determine whether the thermal status bit of at least one memory die of the plurality of memory dies is an active thermal status bit;
reduce an operating performance of the at least one memory die in response to determining that the thermal status bit of the at least one memory die of the plurality of memory dies is the active thermal status bit;
poll the at least one memory die at a second predetermined rate in response to determining that the thermal status bit of the at least one memory die of the plurality of memory dies is the active thermal status bit;
determine whether the thermal status bit of the at least one memory die of the plurality of memory dies is not the active thermal status bit; and
increase the operating performance of the at least one memory die to a normal operating performance in response to determining that the thermal status bit of the at least one memory die of the plurality of memory dies is not the active thermal status bit.
