It’s one thing to create your own relay-based computer; that’s already impressive enough, but what really makes [DiPDoT]’s ...

A sheet of graphene sandwiched between electrolytes can host independently tunable proton and electron currents — setting the stage for a device that serves both computer-memory and logic functions.

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...
