A flash memory 100 capable of reducing electric fields applied to the word lines on a memory array and reducing a chip area, includes a memory array 110, a word line decoder 120 disposed at an end of the memory array on the row direction, selecting a predetermined memory block in the memory array according to an address signal, and outputting a selecting signal to the selected memory block, and a word line drive circuit 130 comprising a switch circuit arranged between the memory arrays 110A and 110B and switching the application of the work voltage to a memory cell according to the selecting signal, and a pump circuit raising the voltage level of the selecting signal. The word line decoder 120 has lines WR(i) to transmit the selecting signals. The lines WR(i) are connected to the switch circuit of the word line drive circuit 130. |
