Embedded STT-MRAM for energy-efficient and cost-effective mobile systems

Abstract

STT-MRAM is a logic-friendly nonvolatile memory that can realize a combination of high speed, low energy, and high endurance. Embedded STT-MRAM is positioned attractively not only for emerging low standby-power connectivity systems such as wearables, IOT (Internet-of-Things), and secure elements, but also for high-performance mobile SOC as an embedded nonvolatile working memory. With recent breakthroughs in CoFeB-based perpendicular magnetic tunnel junctions (MTJ), embedded STT-MRAM has become more energy-efficient and cost-effective in conjunction with robust data retention, scalable for advanced logic nodes.
