Abstract
Magnetic random access memory (MRAM) based on perpendicular magnetic tunnel junctions (pMTJs) is one of the core building blocks for beyond-CMOS technologies. Their inherent non-volatility, rad- hardness and endurance (1016) makes pMTJs extremely competitive for computation-in-memory and other DoD applications where security and ruggedness are of the utmost vitality. To deliver on the potential of MRAM for computation-in-memory, reductions in the energy- and delay characteristics of pMTJs must be demonstrated. Based on interfacial- and bulk perpendicular magnetic anisotropy materials, we demonstrate two novel perpendicular synthetic antiferromagnet (p-SAF) designs for ultra-fast and ultra-low power switching performance: one using interfacial PMA materials and one using bulk PMA materials. Our stacks are compatible with or close to the existing p-MTJ stack and fabrication process, which will make the technology transition to back- end-of-line semiconductor process practical within a 5-10 year time frame.Conference Dates
