Abstract: A method of forming a memory device that in one embodiment may include forming a magnetic tunnel junction on a first electrode using an electrically conductive mask and subtractive etch method. Following formation of the magnetic tunnel junction, at least one dielectric layer is deposited to encapsulate the magnetic tunnel junction. Ion beam etching/Ion beam milling may then remove the portion of the at least one dielectric layer that is present on the electrically conductive mask, wherein a remaining portion of the at least one dielectric layer is present over the first electrode. A second electrode may then be formed in contact with the electrically conductive mask.

Abstract: A magnetoresistive memory cell includes a magnetoresistive tunnel junction stack and a dielectric encapsulation layer covering sidewall portions of the stack and being opened over a top of the stack. A conductor is formed in contact with a top portion of the stack and covering the encapsulation layer. A magnetic liner encapsulates the conductor and is gapped apart from the encapsulating layer covering the sidewall portions of the stack.

Abstract: A magnetic tunnel junction, including a reference layer having a fixed magnetization direction, a first storage layer having a magnetization direction that is adjustable relative to the magnetization direction of the reference layer by passing a write current through said magnetic tunnel junction, and an insulating layer disposed between said reference layer and first storage layer; characterized in that the magnetic tunnel junction further comprises a polarizing device to polarize the spins of the write current oriented perpendicular with the magnetization direction of the reference layer; and wherein said first storage layer has a damping constant above 0.02. A magnetic memory device formed by assembling an array of the magnetic tunnel junction can be fabricated resulting in lower power consumption.
