    摘要: Methods and apparatuses for a magnetic tunnel junction (MTJ) which can be used in as a magnetic random access memory cell are disclosed. The MTJ comprises a free layer and an insulator layer. The MTJ further comprises a pinned layer with a first region, a second region, and a third region. The second region is of a first length and of a first thickness, and the first region and the third region are of a second length and of a second thickness. A ratio of the first thickness to the second thickness may be larger than 1.2. A ratio of the second length to the first length is larger than 0.5. The first thickness may be larger than a spin diffusion length of a material for the pinned layer. So formed MTJ results in increased tunneling magnetic resistance ratio and reduced critical switch current of the MTJ.

    摘要: A magnetoresistive random access memory (MRAM) device and a method of manufacture are provided. The MRAM device comprises a magnetic pinned layer, a compound GMR structure acting as a free layer, and a non-magnetic barrier layer separating the pinned and GMR layers. The barrier layer is provided to reduce the magnetic coupling of the free layer and GMR structure, as well as provide a resistive state (high or low) for retaining binary data (0 or 1) in the device. The GMR structure provides physical electrode connectivity for set/clear memory functionality which is separated from the physical electrode connectivity for the read functionality for the memory device.
