Abstract

In a read-only memory comprising orthogonal pairs of drive and sense lines, inductive coupling is effected by shaping the lines. Ears 11 and 12 are included in the flow and return conductors of a pair of drive lines. Ears 13 and 14 are included in the flow and return conductors of a pair of sense lines. A drive current via 11 and 12 in A produces a current in one direction in the sense lines 13 and 14. A drive current via 11 and 12 in B produces a current in the opposite direction in the sense lines 13 and 14.

Inductive Read Only Memory Bit Pattern

In a read-only memory comprising orthogonal pairs of drive and sense lines, inductive coupling is effected by shaping the lines.

Ears 11 and 12 are included in the flow and return conductors of a pair of drive lines. Ears 13 and 14 are included in the flow and return conductors of a pair of sense lines. A drive current via 11 and 12 in A produces a current in one direction in the sense lines 13 and 14. A drive current via 11 and 12 in B produces a current in the opposite direction in the sense lines 13 and 14.

The pairs of sense and drive lines can be printed on opposite sides of a thin sheet of insulating material, e. g., epoxy glass. A matrix can be built up by placing units such as those shown side-by-side and end-to-end.
