Many superconducting switching devices have been proposed for computer memories including cryotrons [1–3], calotrons [4] persistatrons [5] ryotrons[6], Crowe ceils [7], and the continuous-sheet memory [8], Problems have been slow speed, large heat production, or close tolerance requirements. Currently, crossed-film cryotrons and the continuous-sheet memory appear the most promising.
