Abstract: A memory device includes a lower structure and a plurality of upper structures stacked on the lower structure. The lower structure includes a peripheral circuit, and an upper bonding pad disposed on a top surface of the lower structure. Each of the plurality of upper structures includes a bit line, a through via, and a lower bonding pad disposed on a bottom surface of the upper structures and connected to the through via. Each of upper structures, other than an uppermost upper structure, further includes an upper bonding pad disposed on a top surface thereof and connected to the through via. The bit line includes a gap separating a first portion of the bit line from a second portion thereof in the horizontal direction, and the through via overlaps the gap of the bit line in a plan view.

Abstract: Disclosed is a semiconductor memory device comprising a second substrate on a first substrate and including a lower semiconductor layer and an upper semiconductor layer on the lower semiconductor layer, an electrode structure on the upper semiconductor layer and including a plurality of stacked electrodes, a vertical channel structure that penetrates the electrode structure and is connected to the second substrate, an interlayer dielectric layer that covers the electrode structure, and a cutting structure that penetrates the interlayer dielectric layer and the upper semiconductor layer. The upper semiconductor layer has a first sidewall defined by the cutting structure. The lower semiconductor layer has a second sidewall adjacent to the first sidewall. The first sidewall and the second sidewall are horizontally offset from each other.

Abstract: A three-dimensional semiconductor memory device may include horizontal patterns disposed on a peripheral circuit structure and spaced apart from each other, memory structures provided on the horizontal patterns, respectively, each of the memory structures including a three-dimensional arrangement of memory cells. Penetrating insulating patterns and separation structures may isolate the horizontal patterns from one another. Through vias may extend through the penetrating insulating patterns to connect logic circuits of the peripheral circuit structure to the memory structure.
