Abstract:
A semiconductor integrated circuit, comprising:a first operating potential point; a second operating potential point; a plurality of first logic gates in each of which a first insulated gate field effect transistor of a first conductivity type is included among a plurality of insulated gate field effect transistors connected serially between said first and second operating potential points, while no other insulated gate field effect transistor of the first conductivity type is included among said plurality of insulated gate field effect transistors connected serially between said first and second operating potential points; and a plurality of second logic gates in each of which at least three second insulated gate field effect transistors of the first conductivity type are included among a plurality of insulated gate field effect transistors connected serially between said first and second operating potential points, wherein the absolute threshold voltage of said second insulated gate field effect transistors is smaller than that of said first insulated gate field effect transistor.
