This paper describes a novel Channel Boost Capacitance (CBC) cell technology suitable for highly scaled and fast-programming NAND flash memories. The CBC cell realizes a very high channel boost ratio in self-boosted programming without additional gate control, and drastically improves program disturbance with decreasing design rule, especially less than 0.2 /spl mu/m-rule. This memory cell is essential for realizing highly scaled, and fast-progamming NAND flash memories of 4 Gbit and beyond.
