Computing Fluidly

Computers come in many forms, depending on your definition. We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are ...

Building Diode And Diode-Transistor Logic Gates

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Chiral skyrmion flows enable new approach to nanoscale logic devices

In magnetic materials with antisymmetric exchange interactions, novel particle-like spin textures called magnetic skyrmions can appear and be manipulated by electrons. First observed in 2009, they ...

discrete logic

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

Vertically stacked, low-voltage organic ternary logic circuits including nonvolatile floating-gate memory transistors

Researchers demonstrate “a low-voltage organic ternary logic circuit, in which the organic HTR was vertically integrated with the organic nonvolatile flash memory.” “Multi-valued logic (MVL) circuits ...
