Abstract:
Apparatuses for supplying power supply voltage in a plurality of dies are described. An example apparatus includes: a circuit board; a regulator on the circuit board that regulates a first voltage; a semiconductor device on the circuit board that receives the first voltage through a power line in the circuit board. The semiconductor device includes: a substrate on the circuit board, stacked via conductive balls, that receives the first voltage from the power line via the conductive balls; a plurality of dies on the semiconductor device, stacked via bumps, each die including a first conductive via that receives the first voltage via the bumps; a plurality of pillars between adjacent dies and couple the first conductive vias of the adjacent dies; and a sense node switch circuit that selectively couples one first conductive via of one die among the plurality of dies to the regulator.
