Fully-depleted FBC (floating body cell) with enlarged signal window and excellent logic process compatibility

Overview and future challenges of floating body RAM (FBRAM) technology for 32nm technology node and beyond

“…The write operation of FD FBC is shown in Fig. 2 [8]. Data ''1" is written by creating holes by impact ionization and pushes up the body potential to a high level.…”

“…P À diffused layer on the substrate is used as a plate electrode, which can stabilize the body potential. Salicide process is introduced to reduce the parasitic resistance inside the array device, which is indispensable for high-speed write operation [8]. The write operation of FD FBC is shown in Fig.…”

“…Some kinds of capacitor-less DRAM cell have been proposed and developed [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Floating body cell (FBC) is a promising candidate in view of its simple structure and scalability.…”

Advanced memory concepts for DRAM and nonvolatile memories

“…Because the cell is composed of one transistor, FBC has simple and compact structure. In this case, back gate is used for the charge accumulation in the body [8][9][10]. This structure is the modified double gate configuration.…”
