Abstract
A non-volatile memory device includes a semiconductor substrate having an active region defined by isolation films that extend along a first direction. A control gate line extends along in a second direction perpendicular to the first direction. First and second floating gates are formed on the active region and below the control gate line. An island conductive line is formed between the first and second floating gates and within the isolation films. The island conductive line extends along the first direction and is configured to receive a voltage in order to prevent interference between the first and second floating gates.
