A semiconductor device includes an identification information generation circuit having a power supply control circuit whose output voltage is controlled by a control signal, and a memory array having a first cell power line and a second cell power line. The power supply control circuit outputs a first supply voltage and a second supply voltage to a first cell power line and a second power line, respectively, when the control signal is in a first state, and outputs an intermediate voltage to the first cell power line and the second cell power line when the control signal is in a second state. |
