Abstract
Read/write elements for three-dimensional magnetic memories are disclosed. One embodiment describes an array of integrated read/write elements. The array includes read conductors formed proximate to one of the layers (i.e., storage stacks) of the three-dimensional magnetic memory. The array also includes flux caps formed proximate to the read conductors, and read sensors formed proximate to the flux caps. The array also includes a magnetic pole having a first end contacting the read sensor and a second end opposite the first end. First write conductors are fabricated between the magnetic poles, and second write conductors are also fabricated between the magnetic poles orthogonal to the first write conductors. The first write conductors and the second write conductors form current loops around the magnetic poles.
