Abstract:
1. A semiconductor circuit device comprising: a logic circuit for producing a logical output signal; and a driving circuit for driving a signal line in response to the logical output signal, wherein the logic circuit is given a first positive voltage and a first negative voltage and includes a first logic transistor of a first conductive type and a second logic transistor of a second conductive type inverse to the first conductive type and connected to the first logic transistor to produce the logical output signal from a point of connection between the first and the second logic transistors; and the driving circuit comprising: further wherein the first driving transistor is selected as the at least one of the first and the second driving transistors which is supplied with the electric voltage lower than the first positive voltage (Vcc) and which has the threshold level smaller than that of the first logic transistor in the logic circuit.
