摘要:
A non-volatile memory device includes a substrate and a tunnel insulation layer pattern, such that each portion of the tunnel insulation pattern extends along a first direction and adjacent portions of the tunnel insulation layer pattern may be separated in a second direction that is substantially perpendicular to the first direction. A non-volatile memory device may include a gate structure formed on the tunnel insulation layer pattern. The gate structure may include a floating gate formed on the tunnel insulation layer pattern along the second direction, a first conductive layer pattern formed on the floating gate in the second direction, a dielectric layer pattern formed on the first conductive layer pattern along the second direction, and a control gate formed on the dielectric layer pattern in the second direction.
