From simple transistors to complex systems, this article explains the building blocks of digital logic design. Learn how ...

The PAL family continued to evolve into the late 1980s, with faster, lower-power devices, including ones that could be reprogrammed. The most complex device type developed was probably the PAL22V10, ...

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 ...

For the past several years, researchers have been creating living logic gates, using the genetic on and off switches we've discovered in the biochemical world to create simple logical functions. But ...

Spin doctors: Menno Veldhorst and Andrew Dzurak with their CNOT gate The first quantum-logic device made from silicon has been unveiled by researchers in Australia and Japan. Their controlled-not ...

(a)Working principle of the spin logic device. (b) Transition among diverse magnetic configurations in this heterojunction. By manipulating the direction of the Oersted field, the SOT-induced ...

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...
