Abstract In a magnetic memory device having row windings and, orthogonally aligned word windings, the row windings are arranged in a plurality of parallel planes, with the end of each row winding in the top-most plane being connected at one end to an associated row winding in the next plane therebeneath, the opposite ends of these row windings being connected to the adjacent end of the next plane of row windings therebeneath, and so forth, so as to create an undulating orientation of the row windings. Each planar array of word and row windings is separated from the adjacent plane of word and row windings by a planar magnetic keeper board to minimize the mutual magnetic coupling between row windings and word windings arranged in adjacent planes. The row windings in each plane are maintained in spaced parallel relationship and are electrically insulated from one another by means of tubular insulating tunnel sleeves. The orthogonally oriented word windings are arranged in similar tubular tunnel sleeves and lie in a plane immediately adjacent its associated plane of row windings, with a plane of word windings being provided for each plane of row windings. The opposite ends of the row windings are provided with X- and Yinput terminals for word selection. Additional modular elements of memory assemblies may be connected end to end depending upon the memory capacity desired.
The assembly of claim 1 wherein each of the sets of word lines further comprises inSulation means for electrically insulating each of the word lines in a set from one another.
Claim 2
Dependent Claim
192 words
The magnetic memory assembly of claim 1 further comprising first, second, third and fourth diode switching sets, each being electrically connected to an associated word line of said first, second, third, and fourth sets of word windings, respectively; said first and third diode switching sets being arranged along one side of said first and third word windings and said second and fourth diode switching sets being arranged along the opposite side of said second and fourth wordwindings so that said second and fourth and said first and third diode switching sets are on opposite sides of said word winding arrays; said Y-input selection terminals being electrically connected to selected ones of said diodes in each of said first, second, third, and fourth sets of row windings; said X-input terminal sets each being electrically coupled to opposite ends of the word lines in each of said first, second, third, and fourth sets of word lines wherein the selection of any X-input terminal and any Y input terminal in a given set of word windings electrically connects only one word line in the set of word windings for driving the row windings associated therewith.
