From there, with some size reductions, a Master-Slave J-K Flip Flop, similarly using NAND gates and inverters, can be built. The current state of the project is a working sequencer and counter.

The NAND gate is a circuit that outputs '0' when both inputs are '1', and '0' otherwise, so if you arrange the NAND gate as follows, the Invert circuit is completed.

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.

Hence, in this study, these researchers demonstrated fundamental logic gates (NAND and NOR) using -shaped spin wave waveguides composed of YIG. This element has three inputs and one output. This also ...
