Matrix store wiring pattern

Claim 1

A matrix store, comprising toroidal magnetic storage elements arranged in arrays of rows and columns each array comprising a plurality of rectangular fields each side of said array comprising an integer multiple of two fields, said storage elements in each field being oriented diagonally with respect to said rows and columns and provided with a row selection wire per row and a column selection wire per column and two sense wires, a first plurality of said fields operatively responsive to a first plurality of adjacent row selection wires being identified as higher fields, a second plurality of said fields operatively responsive to a second plurality of adjacent row selection wires being identified as lower fields, each of said sense wires being operatively responsive to one half of the columns of each field said sense wires forming, while crossing each other, at a transition between a higher and lower field, respectively which adjoin each other in the column direction, a bipolar propagation line, all of said storage elements within a field being orientated parallel to a single diagonal to said columns and rows, said storage elements of two fields which adjoin each other in the direction of said rows being orientated according to two different diagonals to said columns and rows, said sense wires being arranged such that they form a spiral having substantially right angle turns, the widths of said turns being substantially equal to the width of said fields in the direction of the rows and consisting of two half-turns which are staggered in each turn with respect to each other, one of said half turns extending between identically sequenced columns in adjacent higher fields, and the other of said half turns extending between columns of different sequence than said one half turn, successive turns overlapping preceding and succeeding turns.
