Logic element and article comprising the element

Disclosed are a novel logic element (designated NORAND), and articles that comprise the element. Exemplarily, the NORAND element comprises three input terminals (A,B,C) and an output terminal (42). If one of the input terminals is at logic 0 then the element functions as a logic NOR unit, and if the terminal is at logic 1 the element functions as a logic AND unit. The novel element thus makes possible reprogrammable and/or self-organizing logic circuits. The NORAND element can be realized with a single active semiconductor device, exemplarily a real space transfer (RST) device.
