Let’s take a look at what it takes to create some fun, out-of-the-ordinary gate implementations. As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR).

In addition, these devices don’t use electricity ... was an OR gate. By combining NOT and OR gates, you can easily make a NAND gate, an AND gate, a NOR gate, and any other logic you can dream ...

While it is accepted that this exponential improvement trend will end, it is still not clear that exactly how dense and fast integrated circuits ... proposed logic gates in comparison with the ...
