Abstract

In the present work, we show that logical state controlling of Josephson memory cells (cryotrons) is possible not only by applying external current impulses, but also by means of magnetic flux impulses. By using methods of mathematical modeling, we studied transitional processes in cryotrons during the switching of their logical state and calculated transitional characteristics for the operational temperature T = 81,2 Ê. Peculiarities of the Josephson cryotrons’ behavior and the effect of the variation of model parameters on direct logical transitions “0”→“1”and inverse logical transitions “1”→“0”are discussed.
