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