Abstract:
Vertical NAND flash memory cell array by TCAT (Terabit Cell Array Transistor) technology is proposed. Damascened metal gate SONOS type cell in the vertical NAND flash string is realized by a unique ‘gate replacement’ process. Also, conventional bulk erase operation of the cell is successfully demonstrated. All advantages of TCAT flash is achieved without any sacrifice of bit cost scalability.
