Original Abstract Submitted
A ferroelectric memory device includes a substrate, a gate structure disposed over the substrate. The gate structure includes a plurality of gate electrode layers spaced apart from each other along a first direction substantially perpendicular to a surface of the substrate. The ferroelectric memory device includes a first electrode pillar and a second electrode pillar that extend along the first direction and are disposed to be spaced apart from each other in a second direction substantially parallel to the surface of the substrate inside a hole penetrating the gate structure, and a device isolation structure disposed to cross the first and second electrode pillars and to separate the gate structure over the substrate. The gate structure further includes a plurality of ferroelectric layers and a plurality of channel layers which are disposed to correspond to the plurality of gate electrode layers.
