Abstract:
Semiconductor memory devices are provided. A semiconductor memory device includes an isolation layer in a first trench and a first gate electrode portion on the isolation layer. The semiconductor memory device includes a second gate electrode portion in a second trench. In some embodiments, the second gate electrode portion is wider, in a direction, than the first gate electrode portion. Moreover, in some embodiments, an upper region of the second trench is spaced apart from the first trench by a greater distance, in the direction, than a lower region of the second trench. Related methods of forming semiconductor memory devices are also provided.

Claim (Index 22):
A semiconductor memory device comprising:\n a substrate; a device isolation layer defining active regions of the substrate; and a gate line structure buried in a trench in the substrate to cross the active regions, wherein the gate line structure comprises a gate insulating layer and a gate electrode in the trench, wherein the gate electrode comprises first electrode portions on the device isolation layer and second electrode portions on the active regions, and wherein the second electrode portions are wider than the first electrode portions.
