This book focuses on the technologies of the floating body cell (FBC), which is regarded as the most probable candidate to replace the conventional 1T-1C DRAM. It covers basic principles, procedures for device structure optimization, operational methods, relations between different applications, and their suitable technology options. One of the authors (Dr. Takashi Ohsawa) is known as the inventor of FBC and presented the award-winning paper at the IEEE International Solid-State Circuits Conference (ISSCC) in 2002 for the cell concept and a memory design using the cell.

"FBC exemplifies the ongoing research efforts in search of scalable dense memory beyond conventional DRAM. The authors introduce fundamental SOI transistor engineering, explain memory array operations and options, and point out directions for future scaling. This book is an excellent summary of FBC research in the past decade and provides a concise reference for this important area of research."

"This is a well-written book by outstanding technologists in the field of floating body (1T DRAM) memory cells. The authors have conducted significant research in this area and written many of the papers that have defined this field. The 1T DRAM is a potential successor to the dynamic RAM (DRAM), which is one of the highest-volume and most successful computer memories in electronics history. This book should be of interest not only to universities but also to industrial technologists seeking a basic understanding of this interesting new memory field."
