Abstract:
A magnetoresistive random-access memory (MRAM) is disclosed. MRAM device has a magnetic tunnel junction stack having a significantly improved performance of the free layer in the magnetic tunnel junction structure. The MRAM device utilizes a precessional spin current (PSC) magnetic layer in conjunction with a perpendicular MTJ where the in-plane magnetization direction of the PSC magnetic layer is free to rotate.

Claim (Index 1):
A magnetic device, comprising\n a synthetic antiferromagnetic structure in a first plane, the synthetic antiferromagnetic structure including a magnetic reference layer, the magnetic reference layer having a magnetization vector that is perpendicular to the first plane and having a fixed magnetization direction; a non-magnetic tunnel barrier layer in a second plane and disposed over the magnetic reference layer; a free magnetic layer in a third plane and disposed over the non-magnetic tunnel barrier layer, the free magnetic layer having a magnetization vector that is perpendicular to the third plane and having a magnetization direction that precesses from a first magnetization direction to a second magnetization direction when a spin-polarized current passes there through, the magnetic reference layer, the non-magnetic tunnel barrier layer and the free magnetic layer forming a magnetic tunnel junction; a non-magnetic spacer in a fourth plane and disposed over the free magnetic layer; precessional spin current means in a fifth plane for causing a magnetization vector with a magnetization component in the fifth plane to follow precession of the magnetization direction of the free magnetic layer, the precessional spin current means being physically separated from the free magnetic layer and electronically coupled to the free magnetic layer by the non-magnetic spacer, wherein rotation of the magnetization component in the fifth plane causes spin polarization of electrons of electrical current passing there through to change in a manner corresponding to the magnetic vector in the fifth plane, thereby creating the spin-polarized current, the spin-polarized current causing spin transfer torque to assist switching of the magnetization vector of the free magnetic layer, the free magnetic layer storing a memory value.
