Claim 12:
13. A semiconductor memory device comprising:
a conductive line extending in a first direction, on a substrate;
an interlayer insulation film that includes a cell trench extending in a second direction intersecting the first direction, on the substrate;
a first gate electrode and a second gate electrode that are spaced apart from each other in the first direction and each extend in the second direction, inside the cell trench;
a separation trench that overlaps the conductive line and extends in the second direction to separate the first gate electrode and the second gate electrode;
a channel layer that extends along the first gate electrode and the second gate electrode and through the separation trench to electrically connect to the conductive line; and
a gate insulation layer interposed between the first gate electrode and the channel layer, and between the second gate electrode and the channel layer.
