Abstract
A CMOS integrated circuit formed in a first semiconductor substrate is supplied with a power through a power control circuit formed in a second semiconductor substrate. The power control circuit is, for example, a flip-flop using the CMOS integrated circuit as one load and detects that a resistance value of the one load is decreased below a predetermined value and decreases power supplied to the CMOS integrated circuit in response to the detection.
