Cryogenic Elements

in computer technology, memory and logical elements whose action is based on superconductivity. The first cryogenic elements (cryotrons, which consist of a tantalium gate wire with niobium control coil) were proposed by the American scientist D. A. Buck in 1955. In 1960 cryogenic memory elements were built using superconducting film.

Cryogenic elements are simple in design, small in size, and inexpensive. Insignificant energy losses make it expedient to use cryogenic elements in very large-capacity memory units, especially associative ones, with very small dimensions and low energy consumption.
