The semiconductor industry seeks to replace traditional volatile memory devices with improved non-volatile memory devices. The increased demand for a significantly advanced, efficient, and non-volatile data retention technique has driven the development of integrated magnetic memory structures. In one aspect, the present teachings relate to magnetic memory structure fabrication techniques in a high density configuration that includes an efficient means for programming high density magnetic memory structures.

Double density MRAM with planar processing

A monolithically formed ferromagnetic thin-film memory is disclosed that has local shielding on at least two sides of selected magnetic storage elements. The local shielding preferably extends along the back and side surfaces of a word line and/or digital lines of a conventional magnetic memory. In this configuration, the local shielding not only may help reduce externally generated EMI, internally generated cross-talk and other unwanted fields in the magnetic bit region, but may also help enhance the desired magnetic fields in the bit region.
