Memories for the Intelligent Internet of Things

BETTY PRINCE, PHD has over thirty years of experience in the semiconductor industry, having worked with Texas Instruments, N.V. Philips, Motorola, R.C.A., and Fairchild. She is currently CEO of Memory Strategies International, Leander, Texas, USA. She holds patents in the memory, processor and interface designs. DAVID PRINCE has worked with the memory reports written by Memory Strategies International for the last eighteen years. He holds degrees in Computer Science, Physics, and Astronomy from the University of Texas.

Overall, this book is very informative and useful for engineers and scientist working in the semiconductor industry or, more specifically, on memory technologies. It gives a state-of-the-art overview on memories in IoT applications. Moreover, it provides a good introduction into the IoT applications and the demands for memories in IoT. - Stephan Menzel, Peter Grünberg Institute, Germany In their new book, Memories for the Intelligent Internet of Things, Betty Prince, with her co-author David Prince, once again deliver to her high standards of content: the book provides the essential details from a whopping 456 technical articles and refereed papers on every memory technology imaginable, from common flash memory to roll-printed organic polymers�This book will prove useful to anyone who needs to rapidly gain a broad understanding of the Intelligent IoT and all of the memory types that it can potentially use. - Jim Handy, OBJECTIVE ANALYSIS: Semiconductor Market Research, USA Industrial maturity usually goes hand in hand with extreme specialization. The IoT driven renaissance in new memory technologies however calls out for a treatment that is both broad and deep. Luckily two of the few polymaths in the area have done it proud. �Memories for the Intelligent Internet of Things� by Betty and David Prince is the best so far. With almost five hundred references and an excellent first chapter that explains the Intelligent IoT using �Smart Cities� to set the scene, all of the incumbent and new solid-state memory technologies are covered: Flash, EEPROM, FeRAM, RRAM, MRAM, PCM, SONOS, MONOS, CB-RAM. It�s all here. From device cross sections all the way to system implementation. I heartily recommend this book to anyone interested in this area, from academics and engineers working in the area to those curious about solid-state memories and what is driving their development. The shaking memory hierarchy has been explained. - Andrew Walker - CEO/Founder of Schiltron Corporation; VP of Spin Memory
