Here, we address these issues, advancing the art of engineering living digital circuits by focusing on two main engineering goals. First, we built a universal, single-gene NOR logic gate ...

For example, the Apollo guidance computer developed in the early 1960s consisted of a circuit comprising a large number of the same type of triple-input NOR gates (a Micrologic chip) 9.

It’s a surprise then to find that a working CPU can be made with just a single NOR gate — which is what ... refreshingly simple and understandable circuit, it has 32k of RAM and a 32k EPROM ...

NOR gates are functionally complete, meaning one can assemble them in different arrangements to make any kind of information processing circuit. The UW engineers did all this using DNA instead of ...

The output of each circuit was made observable by having the last NOR gate drive the expression of the fluorescent GFP protein. The researchers assembled up to seven NOR gates into working ...

However that is not a vital parameter for any glitch free mux when used in various common functions. Instead of CG cell (CG1 and CG2) if simple NOR gate circuit is used to gate and un-gate clocks, the ...

Taking things down a level and breaking the component AND, OR, and NOR gates down to their underlying analog circuits adds some complexity, but the flow of electrons is still pretty understandable.

Our design utilizes the front and back gates of an FDSOI FET as the input terminals and proposes the dynamic logic gates (like; NAND, NOR, AND, OR, XOR, and XNOR) and circuits (like; half adder and ...

Fixed memory jumped to 24K and then finally to 36K words, and erasable memory had a final configuration of 2K words. The AGC system was built by Raytheon, and each system used about 4,000 “Type-G” ...
