Abstract
A three-dimensional semiconductor memory device may include a first conductive line extending in a first direction, a second conductive line extending in a second direction crossing the first direction, a cell stack at an intersection of the first and second conductive lines, and a gapfill insulating pattern covering a side surface of the cell stack. The cell stack may include first, second, and third electrodes sequentially stacked, a switching pattern between the first and second electrodes, and a variable resistance pattern between the second and third electrodes. A top surface of the gapfill insulating pattern may be located between top and bottom surfaces of the third electrode.
