Not [Alexander Shabarshin] though. He’s set himself the task of creating an entire CPU solely from NAND gates, and he’s using 74F00 chips to give a hoped-for 1MIPS performance. His design ...

With the two diodes reversed and a 910 Ohm resistor removed, a NOR gate is created. The next step was to build a S-R latch using the NAND gates and inverters, which holds some basic memory.

We will install a NAND gate on the purple ... the value inverted by the NAND gate is output to the AND gate and then inverted. It can be arranged more simply by using the Invert circuit.

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.
