Vacuum tubes replaced relays as the main elements for computation. A simplified circuit that implements the NOR logic gate, which only outputs 1 when both inputs are o, is show at the right.

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 ...

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 ...

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 ...

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 ...

Instead of CG cell (CG1 and CG2) if simple NOR gate circuit is used to gate and un-gate clocks, the problem disappears. Below circuit and timing diagram delineates the behavior. Figure 5: Solution 2 ...

a simple logic gate such as a NAND and a NOR gate can be readily implemented using EPAD MOSFETs. While digital logic circuit implementation is not the primary application focus for the EPAD MOSFET ...

The AGC system was built by Raytheon, and each system used about 4,000 “Type-G” (3-input NOR gate) circuits. They acquired 200,000 units at $20-30 each; the AGC was the largest user of ICs through ...
