However feasible on-chip integrated logic units and devices still have been limited by its size, quality, scalability, and reliability. Here we demonstrate all-passive on-chip optical AND and NAND ...

The 8721 PLA, or programmable logic array, was one of the chips that had to be invented to make the Commodore 128, the last of the 8-bit computers that formed the leading edge of the early PC revol… ...

One caution here involves gate capacitance. Data sheets may show a typical turn-on time for a charge-pump high-side driver, but manufacturers base that time on a specific load capacitance. Logic ...

Logic Chips Finally there are standard logic chips that may be used as general purpose functions such as the 74×139, two to four decoder with enable.

These chips are used as "glue chips" between ASICs and other ICs typically to reshape and transfer signals. See logic gate and glue logic. THIS DEFINITION IS FOR PERSONAL USE ONLY.

Here we demonstrate that a plasmonic binary NOR gate, a ‘universal logic gate’, can be realized through cascaded OR and NOT gates in four-terminal plasmonic nanowire networks. This finding provides a ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.

This doesn't necessarily help with alternate logic operations, like NOT, but having a larger array of potential tools can only make designing biological circuitry easier. PNAS, 2013.
