<P>PROBLEM TO BE SOLVED: To provide a semiconductor device to function as neuron element, potential generator and logic conversion circuit or the like. <P>SOLUTION: In the potential generator, the source of an N-type MIS transistor 54 and the source of a P-type MIS transistor 56 are connected to each other and connected to an output terminal 55. The drain of the N-type MIS transistor 54 is connected to a power supply voltage feeding part 53 for feeding a power supply voltage VDD and the drain of the P-type MIS transistor 56 is connected to a ground 57 for supplying a ground voltage VSS. Besides, the substrate potential of the N-type MIS transistor 54 is the ground voltage VSS and the substrate potential of the P-type MIS transistor 56 is the power supply voltage VDD. Thus, the semiconductor device is configured as a source follower circuit for taking output out of the sources. By utilizing such a potential generator, the logic conversion circuit is provided for stably switching NOR operation and NAND operation. <P>COPYRIGHT: (C)2003,JPO |
