    摘要: A nonvolatile semiconductor memory device comprises a memory cell array including memory cell transistors having a lamination gate structure are arranged in a matrix manner at the position where a word line and a bit line cross each other. A lower voltage than a threshold voltage is applied to the word line selected at the time of a reading mode in a state that no electrical charge is stored in the floating gate.
