摘要： A body biasing control circuit capable of being shared by a plurality of macro blocks and can independently control body voltages of a plurality of macro blocks. The body biasing control circuit includes a lookup table for storing a plurality of indexes where each index is associated with a body voltage appropriate for an operating state of a corresponding macro block. A control unit receives a corresponding index from the lookup table and generates a plurality of body voltages appropriate for an operating state of a macro block corresponding to the index and supplies the body voltages to the macro block.

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.

摘要： A power gating circuit includes a logic circuit, a switching element and a retention flip-flop. The logic circuit is coupled between a first power rail and a virtual power rail. The switching element selectively couples the virtual power rail to a second power rail in response to a mode control signal indicating an active mode or a standby mode. The retention flip-flop selectively performs a flip-flop operation or a data retention operation in response to a voltage of the virtual power rail.
