Most if not all of the standard logic blocks come in an inverted form also such as the NAND gate shown here. The ability to invert logic functions is so useful in real life that I probably used at ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.

The polymorphic logic gate is realized with three-gated Reconfigurable Field Effect Transistors. Fabrication and electrical characteristics of the elements are discussed. To validate the presented ...
