The invention relates to a semiconductor logic element comprising a field effect transistor of the first conductivity type and a field effect transistor of the second conductivity type. A gate of the first FET is an input of the semiconductor logic element, a drain of the second FET is referred to as the output of the semiconductor logic element and a source of the second FET is the source of the semiconductor logic element. By applying applicable potentials to the terminals of the field effect transistors it is possible to influence the state of the output of the logic element. The invention relates also to different kinds of logic circuitries comprising the described logic element.
