Abstract
A method for making magnetic random access memories (MRAM) which reduces heat conduction from memory cells in an MRAM array. The method uses grid of bit and word lines for selectively accessing data in the array of magnetic memory cells. The grid has a plurality of thermally and electrically resistive portions which provide connections to the magnetic memory cells. The resistive portions increase the thermal resistance for heat generated by each memory cell and during operation provide localized heating of active memory cells to ease cell state switching.
