Claim 10:
11. A semiconductor package, comprising:
a plurality of first semiconductor structures stacked on a package substrate, wherein the first semiconductor structures of the plurality of first semiconductor structures are offset from each other in a first direction; and
a plurality of first adhesive layers disposed between pairs of first semiconductor structures of the plurality of first semiconductor structures,
wherein each of the plurality of first semiconductor structures includes a first memory chip and a first peripheral circuit chip in contact with a part of a top surface of the first memory chip,
wherein each of the plurality of first adhesive layers contacts the first memory chip, and each of the plurality of first adhesive layers is spaced apart from the first peripheral circuit chip,
wherein the first memory chip includes:
a first semiconductor substrate that includes a cell array region and a connection region;
a plurality of electrode layers and a plurality of inter-electrode dielectric layers that are alternately stacked on the first semiconductor substrate and form a stepwise shape on the connection region;
a plurality of vertical patterns disposed on the cell array region, the vertical patterns penetrating the plurality electrode layers and the plurality of inter-electrode dielectric layers;
a planarized dielectric layer covering ends of each of the plurality of electrode layers and ends of each of the plurality of inter-electrode dielectric layers on the connection region; and
a plurality of cell contacts penetrating the planarized dielectric layer and the plurality of inter-electrode dielectric layers to come into contact with corresponding electrode layers, of the plurality of electrode layers, on the connection region,

wherein the first peripheral circuit chip overlaps the plurality of cell contacts and does not overlap at least one of the plurality of vertical patterns.
