ABSTRACT:
Memory devices, arrays, and strings are described that facilitate the use of NROM memory cells in NAND architecture memory strings, arrays, and devices. NROM NAND architecture memory embodiments of the present invention include NROM memory cells in high density vertical NAND architecture arrays or strings facilitating the use of reduced feature size process techniques. These NAND architecture vertical NROM memory cell strings allow for an improved high density memory devices or arrays that can take advantage of the feature sizes semiconductor fabrication processes are generally capable of and yet do not suffer from charge separation issues in multi-bit NROM cells.
