Abstract: A package box assembly is provided. The package box assembly includes a first box comprising an accommodation portion defined by a plate and a side wall disposed to surround the plate along the periphery of the plate and having a designated height, a second box accommodated in the accommodation portion, a hanger disposed in a first space of the accommodation portion to protrude through an opening formed in the side wall, an elastic member disposed in the first space to press the hanger toward the opening, and a sealing member removably disposed on the side wall to seal the opening. The hanger is accommodated in the first space while being pushed by pressure from the elastic member. In case that the sealing member is removed, the hanger at least partially protrudes to the outside of the first box via the opening by the pushing force of the elastic member.

Abstract: A semiconductor memory device is disclosed. The device may include a stack including gate electrodes stacked on a substrate in a vertical direction and insulating patterns interposed between the gate electrodes, vertical channels passing through the stack and connected to the substrate, a tunnel insulating layer enclosing each of the vertical channels, charge storing patterns provided between the tunnel insulating layer and the gate electrodes and spaced apart from each other in the vertical direction, blocking insulating patterns provided between the charge storing patterns and the gate electrodes and spaced apart from each other in the vertical direction, and a bit line crossing the stack and connected to the vertical channels. The blocking insulating patterns may have a vertical thickness that is greater than that of the gate electrodes.
