비휘발성 메모리 소자 및 이의 구동 방법

Abstract

A non-volatile memory device according to various embodiments of the present invention is characterized in that the non-volatile memory device includes a substrate, a first electrode disposed on the substrate, an insulating layer contacting the first electrode, a semiconductor layer contacting the insulating layer, and a second electrode contacting the semiconductor layer, and is driven using an asymmetrical local energy state (ALES) induced in the semiconductor layer under the condition that at least a portion of the first electrode contacts the semiconductor layer. A method of driving the non-volatile memory device in accordance with various embodiments of the present invention includes inducing an asymmetrical local energy state (ALES) generated due to instantaneous acceleration of electrons injected into the semiconductor layer, and removing the ALES from the semiconductor layer, for recovery of the semiconductor layer.
