Patent ID: 8374025

Claim:
A spin-torque transfer memory random access memory (STTMRAM) element comprising: a fixed layer having a magnetization that is substantially fixed in one direction; a barrier layer formed on top of the fixed layer; a free layer having ‘n’ number of alternating laminates, ‘n’ being greater than one, a laminate made of a magnetic layer and an insulating layer, the magnetic layer being switchable and formed on top of the barrier layer, the free layer capable of switching its magnetization to a parallel or an anti-parallel state relative to the magnetization of the fixed layer during a write operation when bidirectional electric current is applied across the STTMRAM element, magnetic layers of the laminates being ferromagnetically coupled to switch together as a single domain during the write operation, wherein the magnetization of the fixed layer and free layers and the magnetic layers of the laminates have either in-plane or perpendicular anisotropy.
