Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To reduced a penetration current of a logic threshold value detection circuit and to make possible low power consumption by generating applied potential while control potential doesn't show coincidence between a logic threshold value and reference potential and stopping its generation when they agree. SOLUTION: The control potential Vcnt generating subsequently Vsub applied to a semiconductor potential while logic threshold value potential Vthinv outputted from a logic threshold value output circuit 2 doesn't match with the reference potential Vref. When the logic threshold value potential Vthinv matches with the reference potential Vref, its operation is stopped and the substrate potential Vsub at the time is held, and a substrate bias for the logic threshold value output circuit 2 is continuously held by a capacitor, etc. A switch circuit 5 interrupts the penetration current path of the logic threshold value output circuit 2 when it receives a signal as the control potential Vcnt showing the matching of the logic threshold value potential Vthinv with the reference potential Vref. Thus, the penetration current of the logic threshold value output circuit 2 is eliminated, and the low power consumption is obtained.
