Patent ID: 7158398

Claim:
A semiconductor memory device having transfer transistors to apply a voltage to a control electrode of electrically rewritable memory cell transistors, the semiconductor memory device comprising: a first transfer transistor in which one end of a current passage is connected to the control electrode of one of the memory cell transistors and is spaced from an adjacent transfer transistor having one end of a current passage connected to the control electrode of one of the memory cell transistors by a first width; a second transfer transistor in which one end of a current passage is connected to the control electrode of one of the memory cell transistors and is spaced from an adjacent transfer transistor having one end of a current passage connected to the control electrode of one of the memory cell transistors by a second width, the second width being different from the first width; and a first control section which applies an on-voltage to make the first and second transfer transistors conductive, to gates of the first and second transfer transistors.
