Floating body cell structures including an array of floating body cells disposed on a back gate and source regions and drain regions of the floating body cells spaced apart from the back gate. The floating body cells may each include a volume of semiconductive material having a channel region extending between pillars, which may be separated by a void, such as a U-shaped trench. The floating body cells of the array may be electrically coupled to another gate, which may be disposed on sidewalls of the volume of semiconductive material or within the void therein. Methods of forming the floating body cell devices are also disclosed.
