A semiconductor memory device includes a stack of word lines and insulating patterns. Cell pillars extend vertically through the stack of word lines and insulating patterns with memory cells being formed at the junctions of the cell pillars and the word lines. A ratio of the thickness of the word lines to the thickness of immediately neighboring insulating patterns is different at different locations along one or more of the cell pillars. Related methods of manufacturing and systems are also disclosed.

A semiconductor device may include gate structures spaced apart above a top surface of a substrate. The gate structures may include a horizontal electrode extending in a first direction parallel with the top surface of a substrate. An isolation insulating layer may be disposed between the gate structures. A plurality of cell pillars may penetrate the horizontal electrode and connect to the substrate. The plurality of cell pillars may include a minimum spacing defined by a shortest distance between any two of the plurality of cell pillars. The thickness of the horizontal electrode may be greater than the minimum spacing of the cell pillars.

A non-volatile memory device includes gate electrodes stacked on a substrate, a semiconductor pattern penetrating the gate electrodes and connected to the substrate, and a charge storage layer between the semiconductor pattern and the gate electrodes. The charge storage layer includes a first charge storage layer between the semiconductor pattern and the gate electrodes, a second charge storage layer between the first charge storage layer and the semiconductor pattern, and a third charge storage layer between the first charge storage layer and the gate electrodes. An energy band gap of the first charge storage layer is smaller than those of the second and third charge storage layers. The first charge storage layer is thicker than the second and third charge storage layers.
