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.

The new logic family includes a NOR gate constructed using only diodes, resistors, and inductors. The key design feature of these gates is a single diode to switch an RF power supply on and off.

Consequently, nobody has been able to make reliable diodes, transistors or logic gates out of silicon nanowires. Today, Massimo Mongillo et amis at the Universite Joseph Fourier, Grenoble, in ...

The transistor turnson, and the logic-zero voltage at thecollector is approximately 0.6+V L +V CE,where V L is the low voltage and V CE is the collector-to-emitter voltage.When inputs A and B are at ...
