摘要:
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 magneto-resistive element is constructed. A ferromagnetic sense layer is deposited on a surface. The ferromagnetic sense layer is patterned. An etch is performed in preparation for depositing a dielectric layer. The dielectric layer is deposited over the sense layer. A ferromagnetic pinned layer is deposited over the dielectric layer.
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.

An apparatus includes a pavement marker configured to be mounted to a road at a lane line of a lane at known orientation with respect to the lane line; and an RF device carried by the raised pavement marker. The RF device is configured to transmit a directional RF navigation signal and it is positioned relative to the known orientation to transmit the signal across the lane in a direction that is substantially normal to the lane line.

The present disclosure provides a memory cell that includes a resistive memory element disposed between a first conductor and a second conductor, the first conductor and the second conductor configured to activate the resistive memory element. The memory cell also includes a backward diode disposed in series with the memory element between the memory element and either the first conductor or the second conductor.
摘要:
Examples of the present disclosure include non-volatile resistive memory cells and methods of forming the same. An example of a non-volatile resistive memory cell includes a first portion of the non-volatile resistive memory cell formed as a vertically-extending structure on a first electrode, where the first portion comprises at least one memristive material across a width of the vertically-extending structure. The non-volatile resistive memory cell also includes a second portion formed as a vertically-extending memristive material structure on at least one sidewall of the first portion.
