Abstract:
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.
