A high density vertical single transistor gain cell is realized for DRAM operation. The gain cell includes a vertical transistor having a source region, a drain region, and a floating body region therebetween. A gate opposes the floating body region and is separated therefrom by a gate oxide on a first side of the vertical transistor. A floating body back gate opposes the floating body region on a second side of the vertical transistor and is separated therefrom by a dielectric to form a body capacitor.
