In recent times there has been remarkable progress in the development of silicon-based photonic circuit components such as on-chip sources, manipulators, detectors, storage, filtering and multiplexing ...

Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

A new way to make complete and programmable logic circuits that combine both memory and logical processing in a single structure has been unveiled by physicists in Germany. Such structures could lead ...

Logic elements, which are the basis of modern digital technology, are based on the use of Boolean logic. In 1854, George Boole proposed for the first time to investigate logical statements by ...

The new approach is based on magnetic random access memory (MRAM) elements that contain two magnetic layers separated by a spacer. If the magnetic moments of the two layers are parallel, the ...

(Nanowerk Spotlight) The human body so far is the ultimate 'wet computer' - a highly efficient, biomolecule-based information processor that relies on chemical, optical and electrical signals to ...
