Data Storage at the Nanoscale Advances and Applications

In the big data era, data storage is one of the cores in the whole information chain, which includes production, transfer, sharing, and finally processing. Over the years, the growth of data volume has been explosive. Today, various storage services need memories with higher density and capacity. Moreover, information storage in the big data applications should be green, safe, and long life. The storage density of memories was largely enhanced in recent years because of the rapid development of nanotechnology. The minimum feature size of optical, magnetic, and electrical memories is already at the nanometer scale. Furthermore, the interdisciplinary cooperation of nanotechnology can facilitate the development of data storage technology to achieve higher operation speed, lower power consumption, and increased retention time. This book compiles the cutting-edge research progress of nanometer-scale data storage. The main topics covered include optical memory, random access memory, magnetic memory, and hybrid memory. The text emphasizes more practical methods for data storage development and applications.
