摘要： Methods and systems to read a logic value stored in a magnetic tunnel junction (MTJ)-based memory cell based on a pulsed read current, with time between pulses to permit the MTJ to relax towards the magnetization orientation between the pulses, which may reduce build-up of momentum within the MTJ, and which may reduce and/or eliminate inadvertent re-alignment of a magnetization orientation. A sequence of symmetric and/or non-symmetric pulses may be applied to a wordline (WL) to cause a pre-charged bit line (BL) capacitance to discharge a pulsed read current through the MTJ, resulting in a corresponding sequence of voltage changes on the BL. The BL voltage changes may be integrated over the sequence of read current pulses, and a stored logic value may be determined based on the integrated voltage changes. The pre-charged BL capacitance may also serve as the voltage integrator.

摘要： An embodiment includes a magnetic tunnel junction (MTJ) including a free magnetic layer, a fixed magnetic layer, and a tunnel barrier between the free and fixed layers; the tunnel barrier directly contacting a first side of the free layer; and an oxide layer directly contacting a second side of the free layer; wherein the tunnel barrier includes an oxide and has a first resistance-area (RA) product and the oxide layer has a second RA product that is lower than the first RA product. The MTJ may be included in a perpendicular spin torque transfer memory. The tunnel barrier and oxide layer form a memory having high stability with an RA product not substantively higher than a less table memory having a MTJ with only a single oxide layer. Other embodiments are described herein.
