Claim 1

A MAGNETIC MEMORY SYSTEM COMPRISING A PLURALITY OF SUBSTANTIALLY SIMILAR TWO-DIMENSIONAL ARRAYS EACH OF WHICH INCLUDES A PLURALITY OF MAGNETIC CORES EACH HAVING A SUBSTANTIALLY RECTANGULAR HYSTERESIS CHARACTERISTIC AND BEING CAPABLE OF BEING OPERATED IN A TIME-LIMITED, A STEADYSTATE, OR A SATURATED CONDITION AS A FUNCTION OF A MAGNETIC FIELD OF A PREDETERMINED AMPLITUDE-DURATION CHARACTERISTIC, WITH ALL OF SAID CORES ARRANGED IN COLUMNS AND ROWS AND INCLUDING A FIRST PLURALITY OF CONDUCTORS EACH OF WHICH IS INDUCTIVELY COUPLED TO A SEPARATE COLUMN AND A SECOND PLURALITY OF CONDUCTORS EACH OF WHICH IS INDUCTIVELY COUPLED TO A SEPARATE ROW FOR PRODUCING A PLURALITY OF MAGNETIC FIELDS FOR PLACING SAID CORES IN AT LEAST TWO MAGNETIC STABLE STATES AND A THIRD PLURALITY OF CONDUCTORS EACH OF WHICH IS INDUCTIVELY COUPLED TO PREDETERMINED ONES OF SAID CORES FOR SENSING THE MAGNETIC STATE OF SAID CORES, THE IMPROVEMENT COMPRISING: MEANS COUPLED TO EACH OF SAID FIRST PLURALITY OF COLUMN CONDUCTORS FOR CONDUCTING SYMMETRICAL FIRST AND A SECOND, OPPOSITE POLARITY, TIME-LIMITED, READ AND WRITE SIGNALS, RESPECTIVELY; MEANS COUPLED TO EACH OF SAID SECOND PLURALITY OF ROW CONDUCTORS FOR CONDUCTING A CONSTANT BIAS SIGNAL OF SAID FIRST POLARITY AND A TIME-LIMITED DIGIT SIGNAL OF SAID SECOND POLARITY WHEREIN THE FIELD PRODUCED BY SAID READ AND BIAS SIGNALS HAS A SUFFICIENT AMPLITUDE-DURATION CHARACTERISTIC TO DRIVE THE MAGNETIC STATE OF SAID CORES INTO A FIRST STABLE STATE SATURATION CONDITION, THE FIELD PRODUCED BY SAID WRITE AND BIAS SIGNALS HAS AN INSUFFICIENT AMPLITUDE-DURATION CHARACTERISTIC TO DRIVE THE MAGNETIC STATE OF SAID CORES INTO A STABLE STATE SUBSTANTIALLY DIFFERENT FROM SAID FIRST STABLE STATE, AND THE FIELD PRODUCED BY SAID WRITE, BIAS AND DIGIT SIGNALS HAS ONLY A SUFFICIENT AMPLITUDE-DURATION CHARACTERISTIC TO DRIVE THE MAGNETIC STATE OF SAID CORES INTO A SECOND STABLE STATE TIME-LIMITED CONDITION; AND TRANSFORMER MEANS COUPLING SAID READ-WRITE SIGNALS TO SAID FIRST PLURALITY OF COLUMN CONDUCTORS.
