A data storage device includes a non-volatile memory device, which includes a memory cell array including a plurality of memory cells and a control circuit. Each of the memory cells includes a channel layer, a charge trap layer on the channel layer, and a control electrode on the charge trap layer, the charge trap layer being shared by the memory cells. The charge trap layer includes program regions respectively disposed below the control electrodes of the memory cells, and charge spread blocking regions, each of which is disposed between two adjacent ones of the program regions and between two adjacent ones of the control electrodes. The control circuit controls the memory cell array so that a potential barrier is generated in the charge spread blocking regions by charging the charge spread blocking regions with charges having the same polarity as that of program charges stored in the program regions.
