  • Patent number: 10535713
    Abstract: A reactive material erasure element including a reactive material is located between PCM cells and is in close proximity to the PCM cells. The reaction of the reactive material is trigger by a current applied by a bottom electrode which has a small contact area with the reactive material erasure element, thereby providing a high current density in the reactive material erasure element to ignite the reaction of the reactive material. Due to the close proximity of the PCM cells and the reactive material erasure element, the heat generated from the reaction of the reactive material can be effectively directed to the PCM cells to cause phase transformation of phase change material elements in the PCM cells, which in turn erases data stored in the PCM cells.

  • Patent number: 10454024
    Abstract: A magnetic cell includes a magnetic region formed from a precursor magnetic material. The precursor magnetic material included a diffusible species and at least one other species. An oxide region is disposed between the magnetic region and another magnetic region, and an amorphous region is proximate to the magnetic region. The amorphous region includes an attracter material that has a chemical affinity for the diffusible species that is higher than a chemical affinity of the at least one other species for the diffusible species. Thus, the diffusible species is transferred from the precursor magnetic material to the attracter material, forming a depleted magnetic material. The removal of the diffusible species and the amorphous nature of the region of the attracter material promotes crystallization of the depleted magnetic material, which enables high tunnel magnetoresistance and high magnetic anisotropy strength. Methods of fabrication and semiconductor devices are also disclosed.
