Emerging Non-volatile Memory Technologies: Physics, Engineering, and Applications

This book offers a balanced and comprehensive guide to the core principles, fundamental properties, experimental approaches, and state-of-the-art applications of two major groups of emerging non-volatile memory technologies, i.e. spintronics-based devices as well as resistive switching devices, also known as Resistive Random Access Memory (RRAM). The first section presents different types of spintronic-based devices, i.e. magnetic tunnel junction (MTJ), domain wall, and skyrmion memory devices. This section describes how their developments have led to various promising applications, such as microwave oscillators, detectors, magnetic logic, and neuromorphic engineered systems. In the second half of the book, the underlying device physics supported by different experimental observations and modelling of RRAM devices are presented with memory array level implementation. An insight into RRAM desired properties as synaptic element in neuromorphic computing platforms from material and algorithms viewpoint is also discussed with specific example in automatic sound classification framework.

Dr. Lew is a full-time academic staff (Assistant Professor) at the School of Physical and Mathematical Sciences (Physics Division), Nanyang Technological University, Singapore. He received his PhD degree from the University of Cambridge, UK. Dr Lew has been working on magnetism and magnetic materials research for more than ten years in industrial and research laboratories. Prior to joining NTU, he worked as Research Associate at the Cavendish Laboratory. Dr Lew’s research team specializes on spin-electronics or “spintronics” devices: thin film sensor growth, micro- and nano-fabrication, device transport measurement, and micromagnetic modeling.
