Abstract: A magnetic memory device can include a synthetic ferrimagnetic data, a soft reference layer and a tunneling layer. The synthetic ferrimagnetic data layer has a magnetic moment directable to a first orientation and a second orientation. The soft reference layer has a lower coercivity than the synthetic ferrimagnetic data layer. The tunneling layer has electrical resistance qualities which are influenced by magnetic moment orientations of the synthetic ferrimagnetic data layer and the soft reference layer.

Abstract: An integrated digitizing tablet and display apparatus is disclosed. The digitizing tablet portion of the apparatus is comprised of an array of magnetic random access memory (MRAM) cells, wherein each MRAM cell is responsive to an externally applied magnetic field. Each memory cell has a magnetic bit that changes orientation upon application of an externally applied magnetic field to produce an electrical signal based on the orientation of the bit when a second electric field is applied across the array. The display is comprised of an array of pixel cells and each pixel cell is coupled to one of the MRAM cells. The MRAM cell activates the pixel cell by the electrical signal produced by the MRAM cell. Thus, what is achieved is an integrated digitizing tablet and display that has digitizing cells that directly control the display cells without the need for additional processors.

Abstract: This invention provides an asymmetrically patterned magnetic memory storage device. In a particular embodiment at least one magnetic memory cell is provided. Each magnetic memory cell provides at least one ferromagnetic data layer of a first size, the data layer characterized by an alterable orientation of magnetization, an intermediate layer in contact with the data layer and at least one ferromagnetic reference layer of a second size, the reference layer characterized by a reference magnetic field. The reference layer is in contact with the intermediate layer, opposite from and asymmetric to the data layer. The magnetic memory cell is characterized as having only one-end involvement. More specifically, the asymmetric alignment provides that only one set of magnetic poles are in substantial vertical alignment, and as such subject to the strong influence of one another.
