A magnetoresistive device includes a free ferromagnetic layer; a pinned structure; and a spacer layer between the free layer and the pinned structure. The pinned structure may include first, second and third ferromagnetic layers that are ferromagnetically coupled. The first and third layers are separated by the second layer. The second layer has a lower magnetic moment than the first and third layers. In the alternative, the pinned structure may include a single layer of Co50Fe50.

摘要:
A coupled ferromagnetic structure includes a first ferromagnetic layer, a spacer layer on a first surface of the first ferromagnetic layer, and a second ferromagnetic layer on the spacer layer. Interlayer exchange coupling occurs between the first and second ferromagnetic layers. The coupling may be ferromagnetic or antiferromagnetic. Morphology of the first surface is modified to tailor the interlayer exchange coupling. The structure may form a part of a magnetoresistive device such as a magnetic tunnel junction.

A top-pinned magnetoresistive device includes a free ferromagnetic layer; a spacer layer on the free layer; and a pinned ferromagnetic layer on the spacer layer. At least one interface property at an upper surface of the pinned layer is adjusted during fabrication of the magnetoresistive device.

A non-volatile memory module for use in a computer system is disclosed. The non-volatile memory module is capable of storing information indefinitely and can be inserted and removed from the computer system during operation. The non-volatile memory can serve as the main memory within the computer system to hold the operating system and any other programs that are accessed by the computer system during operation.
摘要:
This disclosure provides a computer system with operating system permitting dynamic reallocation of main memory during operation. In a particular embodiment the computer system with operating system are used in connection with non-volatile main memory stores (NMS) such as MRAM. As the NMS is a component of main memory attached directly to the memory bus, the NMS functions at substantially the same speed as traditional volatile memory stores. Reallocation of main memory and use of applications or programs stored on the inserted NMS occurs at speeds orders of magnitude greater than traditional secondary memory devices.

摘要:
An electro-magnetic device, such as magnetic memory device, is disclosed that includes means for structuring, attenuating or eliminating stray fields at the boundaries that produce an offset in the magneto-resistive response. The device comprises a conductive first layer and the attenuating means comprises a sink layer, electro-magnetically coupled to the first layer, to attenuate the stray boundary magneto-resistive offset at a boundary of the first layer during electrical operation.
