摘要:
A method of centering a contact on a layer of a magnetic memory device. In one embodiment, a spacers is formed in an opening surrounding the upper layer and the contact is formed within the spacer. The spacer is formed from an anisotropically etched conformal layer deposited on an upper surface and into the opening.
摘要:
A magnetic memory having memory elements each with two magnetic tunneling junction (MTJ) devices is disclosed. The devices in each element are differentially programmed with complementary data. The devices for each element are stacked one above the other so that the element requires no more substrate area than a single MTJ device.
摘要:
Spin transfer torque memory (STTM) devices with half-metals and methods to write and read the devices are described. For example, a magnetic tunneling junction includes a free magnetic layer, a fixed magnetic layer, and a dielectric layer disposed between the free magnetic layer and the fixed magnetic layer. One or both of the free magnetic layer and the fixed magnetic layer includes a half-metal material at an interface with the dielectric layer.
摘要:
Perpendicular spin transfer torque memory (STTM) devices with enhanced stability and damping are described. For example, a material layer stack for a magnetic tunneling junction includes a fixed magnetic layer. A dielectric layer is disposed above the fixed magnetic layer. A first free magnetic layer is disposed above the dielectric layer. A second free magnetic layer is magnetically coupled with the first free magnetic layer.
