Abstract
An integrated RS flip-flop circuit comprises two cross-coupled inverters which respectively consist of a field effect transistor and a resistor connected in series. Each field effect transistor is connected to an additional logic element whose control input represents the R or the S input, respectively. Realization of a flip-flop circuit on the smallest possible semiconductor is achieved by designing the additional logic elements as hot electron transistors, each of which is combined with one of the field effect transistors to form a common component which assumes two transistor functions but only requires the area of one field effect transistor. The invention is particularly useful in VLSI circuits.
