    摘要: In some embodiments of the invention a non-volatile memory cell is provided with a first electrode, a second electrode, and one or more side layers of a ferroelectric metal oxide and a ferroelectric material layer between the first and second electrodes. The ferroelectric material layer may be provided between, e.g., adjacent, two side layers of a ferroelectric metal oxide or between a single layer of a ferroelectric metal oxide and an electrode. The ferroelectric metal oxide may in some cases include a uniform layered structure such as a bismuth layer-structured ferroelectric material like Bi4Ti3O12. In some embodiments, the ferroelectric material layer is formed at least partially from PbZrxTi1-xO3. A non-volatile memory array including such memory cells is also provided.

    摘要: A magnetic cell includes a ferromagnetic free layer having a free magnetization orientation direction and a first ferromagnetic pinned reference layer having a first reference magnetization orientation direction that is parallel or anti-parallel to the free magnetization orientation direction. A first oxide barrier layer is between the ferromagnetic free layer and the first ferromagnetic pinned reference layer. The magnetic cell further includes a second ferromagnetic pinned reference layer having a second reference magnetization orientation direction that is orthogonal to the first reference magnetization orientation direction. The ferromagnetic free layer is between the first ferromagnetic pinned reference layer and the second ferromagnetic pinned reference layer.
