To meet such a demand, we present a 64Gb multilevel cell (MLC) NAND Flash memory having 533Mb/s DDR interface in sub20nm technology. Large floating-gate (FG) coupling interference and program disturbance are major challenges to impede the scaling of NAND Flash memories in sub-20nm technology node [1]. In this paper, w
