System on chip and temperature control method thereof

摘要

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.

1. A method of controlling a temperature of a semiconductor device, comprising:
detecting, by a temperature sensor, a temperature of the semiconductor device; activating a reverse body biasing operation in which, in response to determining that the detected temperature is greater than a first temperature level, a body bias voltage applied to a substrate of a function block of the semiconductor device is regulated; and activating a thermal throttling operation in which, in response to determining that the detected temperature is greater than a second level that is different than the first temperature level, at least one frequency of a driving clock is provided to the function block of the semiconductor device and a driving voltage applied to the function block of the semiconductor device is regulated.
