    摘要: A method of producing bit-patterned media is provided whereby a shell structure is added on a bit-patterned media dot. The shell may be an antiferromagnetic material that will help stabilize the magnetization configuration at the remanent state due to exchange coupling between the dot and its shell. Therefore, this approach also improves the thermal stability of the media dot and helps each individual media dot maintain a single domain state.

    摘要: Embodiments of the invention provide a multi-terminal resistance device with first and second electrodes, a shared third electrode, and a resistance layer providing first and second current paths between the shared third electrode and the first and second electrodes, respectively. A current state of the device may be programmed by applying one or more electrical signals along the first and/or second current paths to change a resistance of the device. In some embodiments, applying an electrical signal may switch a junction resistance of the first and/or second electrodes and the resistance layer between two or more resistance values. The device may include a shared fourth electrode to provide extra programming capability. In some embodiments, the device may be used to store a data state, to determine a count of multiple electrical signals, or to perform a logic operation between two electrical signals.

    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 tunnel junction cell having a free layer, a ferromagnetic pinned layer, and a barrier layer therebetween. The free layer has a central ferromagnetic portion and a stabilizing portion radially proximate the central ferromagnetic portion. The construction can be used for both in-plane magnetic memory cells where the magnetization orientation of the magnetic layer is in the stack film plane and out-of-plane magnetic memory cells where the magnetization orientation of the magnetic layer is out of the stack film plane, e.g., perpendicular to the stack plane.
