Abstract:
A superconducting cell, comprising:a superconductive storage loop for storing binary information, said superconducting cell having a storing state for storing binary information and a reading state for reading binary information;a read-out loop; anda direct coupling means between the storage loop and the read-out loop, with the direct coupling means having an inductor common to the storage loop and the read-out loop;said storage loop comprising:a first address line directly connected to the storage loop,a second address line magnetically coupled storage loop,a first switchable storage element for switching the superconducting cell into the storing state, when currents on the first and second address lines have same polarity, and into the reading state, when the currents on the first and second address lines have different polarity, anda second switchable storage element for imposing a reading current through the direct coupling means, and passing the reading current to the read-out loop in the reading state for sensing the stored binary information on the first address line.
