Nonvolatile semiconductor memory device
Abstract:
A nonvolatile semiconductor memory device including a memory cell array of memory cells arranged in a matrix, each of which includes a selecting transistor and a memory cell transistor; a column decoder controlling the potential of bit lines; a voltage application circuit controlling the potential of the first word lines; a first row decoder controlling the potential of the second word lines; and a second row decoder controlling the potential of the source line. The column decoder is formed of a circuit whose withstand voltage is lower than the voltage application circuit and the second row decoder.
