PROBLEM TO BE SOLVED: To stabilize the voltage of power source line or the like.SOLUTION: A word line driver 33 supplies a control voltage VPX or a control voltage XDS to a word line WL1 in accordance with a word line selection signal WSEL. The word line driver 33 operates with the control voltages VPX and XDS as operation voltages. A capacitance connection circuit 32 is connected to a floating gate DFG of a dummy cell DC. The capacitance connection circuit 32 is connected to a node N1 between a sector selection circuit 31 and the word line driver 33. The capacitance connection circuits 32 connects and separates the floating gate DFG of the dummy cell DC to/from the node N1 in accordance with an operation mode. |
