MULTI-BIT NON-VOLATILE MEMORY DEVICE, AND METHOD OF OPERATING THE SAME

摘要

A memory device may include a channel including at least one carbon nanotube. A source and a drain may be arranged at opposing ends of the channel and may contact different parts of the channel. A first storage node may be formed under the channel, and a second storage node may be formed on the channel. A first gate electrode may be formed under the first storage node and a second gate electrode may be formed on the second storage node.
