Abstract
Single transistor floating-body DRAM devices have a vertical channel transistor structure. The DRAM devices include a substrate, and first and second floating bodies disposed on the substrate and isolated from each other. A source region and a drain region are disposed under and above each of the first and second floating bodies. A gate electrode is disposed between the first and second floating bodies. Methods of fabricating the single transistor floating-body DRAM devices are also provided.
