Embodiments include a transistor device that comprises a gate electrode and a gate dielectric surrounding the gate electrode. In an embodiment, a source region may be below the gate electrode and a drain region may be above the gate electrode. In an embodiment, a channel region may be between the source region and the drain region. In an embodiment, the channel region is separated from a sidewall of the gate electrode by the gate dielectric. In an embodiment, a capacitor may be electrically coupled to the drain region.
