Reduction of delta noise in coincidentcurrent magnetic matrix storage systems

Claim 1

A COINCIDENT CURRENT MAGNETIC MATRIX SYSTEM COMPRISING A PLURALITY OF FERRITE MEMORY CORES, EACH OF WHICH HAS A SUBSTANTIALLY SQUARE HYSTERESIS LOOP, THE CORES BEING ARRANGED IN ONE PLANE IN ROWS AND COLUMNS; A PLURALITY OF ADDRESS WIRES, ONE FOR EACH ROW AND ONE FOR EACH COLUMN THREADING ALL THE CORES IN THE RESPECTIVE ROW OR COLUMN; AN INHIBIT WIRE FOR THE PLANE THREADING ALL THE CORES IN THE PLANE; AN OUTPUT WIRE THREADING ALL THE CORES IN SUCH A MANNER AS TO MINIMIZE INTERFERENCE FROM HALF SELECTED CORES; MEANS FOR SELECTING A PARTICULAR CORE, FOR READING FOLLOWED BY WRITING, BY THE APPLICATION OF A HALF-READ PULSE COINCIDENTALLY TO THE TWO ADDRESS WIRES CORRESPONDING TO THE ROW AND COLUMN OF THE PARTICULAR CORE FOLLOWED BY THE APPLICATION OF A HALF-WRITE PULSE COINCIDENTALLY TO THE TWO ADDRESS WIRE CORRESPONDING TO THE ROW AND COLUMN OF THE PARTICULAR CORE; MEANS FOR APPLYING A HALF-INHIBIT PULSE OF THE INHIBIT WIRE IN COINCIDENCE WITH AND IN OPPOSITION TO THE HALF-READ OR THE HALF-WRITE PULSES WHEN IT IS REQUIRED TO INHIBIT READING OR WRITING-IN A SELECTED CORE; AND MEANS FOR APPLYING AN ADDITIONAL HALF-READ PULSE TO EACH OF THE SAID TWO ADDRESS WIRES PRIOR TO THE APPLICATION OF THE HALF-READ PULSE, SAID ADDITIONAL HALF-READ PULSES BEING MUTUALLY NON-COINCIDENT IN TIME.
