Magnetic multilayer structures, such as magnetic or magnetoresistive tunnel junctions (MTJs) and spin valves, having one or more spin diffusion layers to diffuse the electron spins outside the MTJ or spin valve structure to reduce the spin transfer switching current for switching the free layer.

Current-switched spin-transfer magnetic devices with reduced spin-transfer switching current density

A method and system for providing a magnetic memory. The magnetic memory includes magnetic storage cells in an array, bit lines, and source lines. Each magnetic storage cell includes at least one magnetic element. The magnetic element(s) are programmable by write currents driven through the magnetic element(s). Each magnetic element has free and pinned layer(s) and a dominant spacer. The magnetic memory is configured such that either the read current(s) flow from the free layer(s) to the dominant spacer if the maximum low resistance state read current divided by the minimum low resistance state write current is greater than the maximum high resistance state read current divided by the minimum high resistance state write current or the read current(s) flow from the dominant spacer to the free layer(s) if the maximum low resistance state read current divided by the minimum low resistance state write current is less than the maximum high resistance state read current divided by the minimum high resistance state write current.

Current driven switching of magnetic storage cells utilizing spin transfer and magnetic memories using such cells having enhanced read and write margins

Devices and techniques for applying a resonant action by an applied oscillating magnetic field to a magnetic tunnel junction (MTJ) and an action of an applied DC current across the MTJ to effectuate a switching of the MTJ when writing data to the MTJ.
