NONVOLATILE SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: A nonvolatile semiconductor memory device is provided to reduce a current which flows into a non-selected memory string and to accurately read data. CONSTITUTION: A plurality of first memory transistors are serially connected to a plurality of first memory strings. One end part is connected to one end of the first memory string. A first wire is mutually connected to the other end part of a plurality of first selecting transistors. One end of the first wire is connected to a switching circuit.
