ABSTRACT:
A nonvolatile semiconductor memory device includes a memory cell array having a plurality of cell units each including a preset number of memory cells and select gate transistors on drain and source sides. The nonvolatile semiconductor memory device includes a voltage control circuit to prevent occurrence of an erroneous write operation due to excessively high boost voltage of a channel when “1” is written into the memory cell.
