High floating-gate (FG) to FG coupling and lithography limitations have been preventing 2D-NAND flash from further reduction in die size, (e.g., there is no ISSCC paper discussing a 3b/cell 2D-NAND after 2013 [1,2]). Alternatively, since high-density multi-stacked 3D-flash was first introduced as BiCS flash [3], recent dramatic innovations in 3D-flash(More)
