    摘要: An exemplary memory array including a plurality of memory cells, each of the memory cells comprises a first ferromagnetic layer, a second ferromagnetic layer spaced apart from the first ferromagnetic layer by a non-magnetic separating layer and being magnetically coupled to the first ferromagnetic layer by demagnetizing fields from the first ferromagnetic layer, a spacer layer above the second ferromagnetic layer, and a reference layer above the spacer layer. The first ferromagnetic layer, non-magnetic separating layer, and second ferromagnetic layer in combination function as a data layer of the memory cell.

    摘要: 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.

    摘要: A method of fabricating a magnetic random access memory (MRAM) device is disclosed. The method reduces the number of mask steps and processing steps required to fabricate the MRAM device. A first conductive layer and a sense layer are patterned in a first mask step. A subsequent etching step forms a bottom electrode and a sense layer that are continuous with each other in a first direction. A second conductive layer and a plurality of layers of material required to form a magnetic tunnel junction stack are patterned in a second mask step. A subsequent etching step forms a top electrode and a plurality of layers of material that are continuous with each other in a second direction, and a plurality of discrete sense layers. The discrete sense layers and the plurality of layers of material define a plurality of magnetic tunnel junction devices.
