ABSTRACT:
A switch for selecting internal circuit options in MOS/LSI circuits without altering the circuit layout on a semiconductor chip by selectively implanting channels of field-effect transistors such that selected circuit-option lines are coupled to a designated line. Switches may be constructed with multiple inputs and a single output, or with multiple outputs and a single input, or with multiple inputs and multiple outputs. A bidirectional switch may also be constructed by controlling the gate potential of each transistor connecting one of the option lines to the designated line with a two-input switch for selecting either a high or a low gate potential.
