    Abstract: A three-dimensional semiconductor memory device may include a first stack block including first stacks arranged in a first direction on a substrate, a second stack block including second stacks arranged in the first direction on the substrate, and a separation structure provided on the substrate between the first stack block and the second stack block. The separation structure may include first mold layers and second mold layers, which are stacked in a vertical direction perpendicular to a top surface of the substrate.

    Abstract: A semiconductor device includes a lower structure; a first upper structure including lower gate layers on the lower structure; a second upper structure including upper gate layers on the first upper structure; separation structures penetrating the first and second upper structures on the lower structure; a memory vertical structure penetrating the lower and upper gate layers between the separation structures; and a first contact plug penetrating the first and second upper structures and spaced apart from the lower and upper gate layers. Each of the first contact plug and the memory vertical structure includes a lateral surface having a bent portion. The bent portion of the lateral surface is disposed between a first height level on which an uppermost gate layer of the lower gate layers is disposed and a second height level on which a lowermost gate layer of the upper gate layers is disposed.
