  • System on chip and temperature control method thereof
    Patent number: 9459680
    Abstract: A temperature control method of a semiconductor device is provided. The temperature control method includes detecting a temperature of the semiconductor device; activating a reverse body biasing operation in which a body bias voltage applied to a function block of the semiconductor device is regulated, when the detected temperature is greater than a first temperature level; and activating a thermal throttling operation in which at least one of a frequency of a driving clock provided to a function block of the semiconductor device and a driving voltage applied to the function block of the semiconductor device is regulated, when the detected temperature is greater than a second temperature level that is different than the first temperature level.
