Abstract

An integrated circuit device includes a transistor array having a vertical stack of independently controllable gate electrodes therein. A first semiconductor channel region is provided, which extends on a first sidewall of the vertical stack of independently controllable gate electrodes. A first electrically insulating layer is also provided, which extends between the first semiconductor channel region and the first sidewall of the vertical stack of independently controllable gate electrodes. Source and drain regions are provided, which are electrically coupled to first and second ends of the first semiconductor channel region, respectively.
