Patent ID: 8422286

Claim:
A spin-torque transfer memory random access memory (STTMRAM) element, employed in a STTMRAM array, where the STTMRAM element received electric current for storage of digital information, the STTMRAM element comprising: a magnetic tunnel junction (MTJ) including, an anti-ferromagnetic (AF) layer; a fixed layer having a magnetization that is substantially fixed in one direction and that comprises a first magnetic layer, an AF coupling layer and a second magnetic layer; a barrier layer formed upon the fixed layer; a free layer comprised of a low-crystallization temperature magnetization layer made of an alloy of CoFeB—Z where Z is made of one or more of titanium, (Ti), yittrium (Y), zirconium (Zr), and vanadium (V), the free layer having a magnetization that is switchable; wherein during a write operation, a bidirectional electric current is applied across the STTMRAM element to switch the magnetization of the free layer between parallel and anti-parallel states relative to the magnetization of the fixed layer.
