Claim 1

A MAGNETIC MEMORY ELEMENT PROVIDING NONDESTRUCTIVE READOUT, COMPRISING: FIRST AND SECOND OPEN FLUX PATH TYPE MULTI-STABLE-STATE CORES OF SUBSTANTIALLY SIMILAR FERROMAGNETIC MATERIAL HAVING UNIAXIAL ANISOTROPY PROVIDING A MAGNETIC EASY AXIS ALONG WHICH EACH CORE''S REMANENT MAGNETIZATION SHALL RESIDE AND WHEREIN EACH CORE IS DISPOSED IN A MAGNETICALLY INTERACTING RELATIONSHIP WITH SAID CORES'' AXES SUBSTANTIALLY ALIGNED AND WITH EACH CORE ONLY PARTIALLY CLOSING THE OTHERWISE OPEN FLUX PATH OF THE OTHER, EACH OF SAID CORES EFFECTING A DEMAGNETIZING FIELD IN THE AREA OF THE OTHER; MEANS INDUCTIVELY COUPLED TO SAID CORES FOR CAUSING THE MAGNETIZATION OF SAID CORES TO BE ALIGNED IN A SELECED ONE OF SAID STABLE-STATES; MEANS INDUCTIVELY COUPLED TO SAID CORES FOR PRODUCING A RESPECTIVE ADDITIVE FIELD INTENSITY IN THE AREA OF SAID FIRST CORE FOR CAUSING AN ENHANCED EFFECT UPON THE MAGNETIZATION OF SAID FIRST CORE BUT A REPECTIVE SUBTRACTIVE FIELD INTENSITY IN THE AREA OF SAID SECOND CORE FOR CAUSING A MINIMIZED EFFECT UPON THE MAGNETIZATION OF SAID SECOND CORE; SENSE MEANS COUPLED AT LEAST TO SAID FIRST CORE, SAID ENHANCED EFFECT UPON THE MAGNETIZATION OF SAID FIRST CORE PRODUCING AN OUTPUT SIGNAL IN SAID SENSE MEANS THE POLARITY OF WHICH IS INDICATIVE OF THE SAID SELECTED ONE STABLE-STATE.
