Classification: CPC H | IPC H

Claim 8:
9. A chip comprising:
a temperature sensor sensing a temperature of the chip to generate a temperature voltage;
a heating circuit receiving the temperature voltage, comparing the temperature voltage with a first threshold voltage to generate a heating control signal, comparing the temperature voltage with a second threshold voltage, and generating a comparison signal according to a comparison result between the temperature voltage and the second threshold voltage, wherein the first threshold voltage is greater than the second threshold voltage; and
a processor coupled to the heating circuit, wherein the heating circuit provides the comparison signal as a reset signal to the processor,
wherein when the temperature voltage is less than the first threshold voltage, the heating circuit generates thermal energy to heat the chip according to the heading control signal, and
wherein when the temperature voltage is less than the second threshold voltage, the reset signal has a disabled voltage level to stop the processor from operating.
