A NAND flash memory cell row includes first and second stacked gate structures, control and floating gates, intergate dielectric layer, tunnel oxide layer, doping regions and source/drain regions. The first stacked gate structures has an erase gate dielectric layer, an erase gate and a first cap layer. The second stacked gate structure has a select gate dielectric layer, a select gate and a second cap layer. The control gate is between each of the first stacked gate structures, and between each of the second stacked gate structures and adjacent first stacked gate structure. The floating gate is between the control gate and substrate. The inter-gate dielectric layer is between the control and floating gates. The tunnel oxide is between the floating gate and substrate. The doping regions are under the first stacked gate structure, and the source/drain regions are in the exposed substrate.
