Abstract: Provided is a semiconductor device including a target circuit, a monitoring circuit, and a voltage controller. The target circuit includes a transistor. The monitoring circuit is configured to measure a temperature of the target circuit or measure a delay time between an input and an output of the target circuit. The voltage controller is configured to adjust a driving voltage for driving the target circuit or a back-bias voltage for adjusting a threshold voltage of the transistor by referring to at least one of the temperature and the delay time. As the temperature increases, the delay time decreases.

Abstract: An Ultra Low Voltage (ULV) digital circuit includes a logic circuit comprising a plurality of logic gates and a plurality of buffered interconnects for connecting between the plurality of logic gates, a temperature sensor configured to detect a temperature of the logic circuit, and a voltage controller configured to control a driving voltage provided to the logic circuit in order to reduce a power consumption of the logic circuit based on the detected temperature. Each of the plurality of logic gates and buffered interconnects reduces a signal delay as a temperature increases.

Abstract: Provided is a network-on-chip (NoC). The NoC includes a plurality of routers configured to receive power through each corresponding power gating switch, and a controller configured to control a power gating switch of each of the plurality of routers based on temperature information provided from each of the plurality of routers and control a driving clock of the plurality of routers. The controller controls the power gating switch to turn off at least one first router by referring to the temperature information and over-scale a clock frequency of at least one turned-on second router.
