The nonvolatile semiconductor memory device includes plural bit lines extending in a first direction, and a memory cell that includes plural blocks each having plural NAND strings each of which includes a group of memory cells connected in series with one another and selecting transistors connected to the respective ends of the memory cell group. One ends of current paths in ones of the selecting transistors are connected to the bit lines, while one ends of current paths in the other selecting transistors are connected to a source line. The nonvolatile semiconductor memory device further includes a memory cell array and a voltage control circuit that is disposed in the memory cell array in a manner of bisecting the memory cell array and that charges or discharges the bit lines."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonvolatile semiconductor memory device","description":"A nonvolatile semiconductor memory device for raising operating speed is provided.
