1 Citation (Scopus)


This book is the first monograph written comprehensively and exclusively for the technologies of the floating body cell (FBC), which is regarded as the most probable candidate to replace the conventional 1T-1C DRAM cell that faces the difficulty in scaling due to the capacitor whose capacitance must be kept constant throughout generations. Readers are provided with the information in this burgeoning field that is necessary in developing memories using FBC through the understanding of 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 the presenter of 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. This book covers the operational principles and features of FBC in comparison with the conventional 1T-1C DRAM cell, the mechanism how the signal of FBC is generated, the device parameter selection that contributes to enhance the signal, scaling, sense amplifier design and various applications in both embedded and standalone memories.
