As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

A study on logic gates titled "Light-field control of real and virtual charge carriers" has been published in the journal Nature. Researchers have developed a new kind of logic gate, the fundamental ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

A team of researchers at the University of New South Wales (UNSW) in Sydney, Australia claim to have overcome a crucial hurdle in quantum computing. Their pioneering work has resulted in the building ...

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 ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...

CUPERTINO, Calif. — Any survival handbook for Silicon Valley startups trying to sell intellectual property might well include a final passage that goes like this: If all else fails, build and sell ...

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

Radiation from space is becoming a chip design issue, as feature sizes shrink and chip frequencies increase to the point where logic circuits as well as memories become prone to switching unexpectedly ...
