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 up. Mechanical computing is decidedly old school, but not at these scales.

As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR). Electronic gates operate on two nominal voltages, normally 0 V and 5 V, representing the logic 0 ...

3(a): Proposed NAND Gate for Approximate Computing Fig. 3(b): Spice waveforms depicting proposed NAND e.g. one supply node has been replaced with the signal ‘A’ which is not a path formed from supply ...

NAND Flash is named after the NAND (NOT-AND) logic gate, which is used in its basic architecture. The term "NAND" is derived from the way the memory cells are organized in a series-connected structure ...

The NAND and NOR designations actually refer to the logic circuits on the chips (for more details, see flash memory and logic gate). Traditional flash memory has a single layer of cells ...

The achievement of 294 total layers (or gates per vertical NAND string) not only positions YMTC as a strong contender in the global NAND flash memory market but also signals significant progress ...
