Partyka, M. Tyhanskyj] In this work, we consider controlling of logical states of Josephson memory cells (cryotrons) based on superconductor-insulator-superconductor (SIS) Josephson tunnel junctions by external current impulses. A mathematical model for the transitional processes that take place during direct logical transitions "0”→"1” and inverse logical transitions "1” → "0” is proposed. By means of mathematical modeling, we investigate transitional processes in cryotrons during the change of their logical state and obtain their transitional characteristics for operational temperatures T 1=11.6K and T 2=81.2K, close to the boiling temperatures of helium and nitrogen, respectively. It is shown that such memory cells can efficiently operate under the temperature T 2=81.2K. The behavior of the Josephson cryotrons as well as their operational stability is explored.
