ABSTRACT:
A small, very low cost, wide margin core memory couples a return current drive scheme with a crossover-free sense winding extending parallel to the Y drive conductors to eliminate the assembly time and wasted substrate space associated with sense winding crossovers. The return currents generate small noise signals which cancel with partial select noise signals to provide noise signals comparable to a 3 wire, 3D bow tie sense winding.
