Some bizarre ways of building logic gates also exist. Conway’s Game of Life, perhaps the most well known cellular automaton, has been shown to be a Universal Turing Machine, meaning that ...

A technical paper titled “Logic-in-Memory Operation of Ternary NAND/NOR Universal Logic Gates using Double-Gated Feedback Field-Effect Transistors” was published by researchers at Korea University.

Section II discusses the implementation of universal basic building blocks: the NAND and the NOR Gates. Section III describes the simulation results for the leakage power and dynamic power of the ...

In addition to a basic “1” and “0” logic state, these gates can also be configured for a tri-state input and output. This is huge; there are only two universal gates when you’re only ...
