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.
