    Abstract: A magnetic cell includes a magnetic region formed from a precursor magnetic material comprising a diffusive species and at least one other species. An amorphous region is proximate to the magnetic region and is formed from a precursor trap material comprising at least one attracter species having at least one trap site and a chemical affinity for the diffusive species. The diffusive species is transferred from the precursor magnetic material to the precursor trap material where it bonds to the at least one attracter species at the trap sites. The species of the enriched trap material may intermix such that the enriched trap material becomes or stays amorphous. The depleted magnetic material may then be crystallized through propagation from a neighboring crystalline material without interference from the amorphous, enriched trap material. This enables high tunnel magnetoresistance and high magnetic anisotropy strength. Methods of fabrication and semiconductor devices are also disclosed.

    Abstract: A magnetic cell includes magnetic, secondary oxide, and getter seed regions. During formation, a diffusive species is transferred from a precursor magnetic material to the getter seed region, due to a chemical affinity elicited by a getter species. The depletion of the magnetic material enables crystallization of the depleted magnetic material through crystal structure propagation from a neighboring crystalline material, without interference from the now-enriched getter seed region. This promotes high tunnel magnetoresistance and high magnetic anisotropy strength. Also during formation, another diffusive species is transferred from a precursor oxide material to the getter seed region, due to a chemical affinity elicited by another getter species. The depletion of the oxide material enables lower electrical resistance and low damping in the cell structure. Methods of fabrication and semiconductor devices are also disclosed.

    Abstract: Some embodiments include a memory cell having a data storage region between a pair of conductive structures. The data storage region is configured to support a transitory structure which alters resistance through the memory cell. The data storage region includes two or more portions, with one of the portions supporting a higher resistance segment of the transitory structure than another of the portions. Some embodiments include a method of forming a memory cell. First oxide and second oxide regions are formed between a pair of conductive structures. The oxide regions are configured to support a transitory structure which alters resistance through the memory cell. The oxide regions are different from one another so that one of the oxide regions supports a higher resistance segment of the transitory structure than the other.
