摘要：Provided is a capacitorless memory device. The device includes a semiconductorsubstrate, an insulating layer disposed on the semiconductor substrate, a storage regiondisposed on a partial region of the insulating layer, a channel region disposed on the

storage region to provide a valence band energy offset between the channel region andthe storage region, a gate insulating layer and a gate electrode sequentially disposed onthe channel region, and source and drain electrodes connected to the channel region anddisposed at both sides of the gate electrode. A storage region unit having differentvalence band energy from a channel region unit is disposed under the channel region unitso that charges trapped in the storage region unit cannot be easily drained. Thus, acharge retention time may be increased to improve data storage capability.
