| 20080232002 | MRAM TUNNEL BARRIER STRUCTURE AND METHODS - A magnetic tunnel junction (MTJ) structure is of the type having a tunnel barrier positioned between a fixed ferromagnetic layer and a free ferromagnetic layer, the tunnel barrier includes a first barrier layer contacting either the fixed ferromagnetic layer or the free ferromagnetic layer. The first barrier layer transmits a high spin polarization and is selected from the group consisting of metal oxides, metal nitrides, and metal oxynitrides. The second barrier layer, which contacts the first barrier layer, has a low barrier height and is selected from the group consisting of metal oxides, metal nitrides, and metal oxynitrides. | 09-25-2008 |
| 20080258247 | SPIN-TRANSFER MRAM STRUCTURE AND METHODS - A spin-transfer MRAM bit includes a free magnet layer positioned between a pair of spin polarizers, wherein at least one of the spin polarizers comprises an unpinned synthetic antiferromagnet (SAF). The SAF may include two antiparallel fixed magnet layers separated by a coupling layer. To improve manufacturability, the layers of the SAF may be non-symmetrical (e.g., having different thicknesses or different inherent anisotropies) to assist in achieving proper alignment during anneal. The total magnetic moment of the SAF may be greater than that of the free magnet layer. | 10-23-2008 |
| 20090085058 | ELECTRONIC DEVICE INCLUDING A MAGNETO-RESISTIVE MEMORY DEVICE AND A PROCESS FOR FORMING THE ELECTRONIC DEVICE - A process of forming an electronic device can include forming a stack including a tunnel barrier layer. The tunnel barrier layer can have a ratio of the metal atoms to oxygen atoms of greater than a stoichiometric ratio, wherein the ratio has a particular value. The process can also include forming a gettering layer having a composition capable of gettering oxygen, and depositing an insulating layer over the gettering layer. The process can further include exposing the insulating layer to a temperature of at least approximately 60° C. In one embodiment, after such exposure, a portion of the gettering layer is converted to an insulating material. In another embodiment, an electronic device can include a magnetic tunnel junction and an adjacent insulating layer lying within an opening in another insulating layer. | 04-02-2009 |
