A semiconductor integrated circuit includes first to eighth column selection transistors and ninth to twelfth column selection transistors. The ninth column selection transistor is connected to the first and second column selection transistors. The tenth column selection transistor is connected to the third and fourth column selection transistors. The eleventh column selection transistor is connected to the fifth and sixth column selection transistors. The twelfth column selection transistor is connected to the seventh and eighth column selection transistors. A first column selection line is connected to gates of the first, third, fifth and seventh column selection transistors. A second column selection line is connected to gates of the second, fourth, sixth and eighth column selection transistors. Third to sixth column selection lines are connected to gates of the ninth to twelfth column selection transistors, respectively.
