Abstract:
A semiconductor package may include a first chip stack, a second chip stack, and a third chip stack. The third chip stack may include third semiconductor chips, the third chip stack coupled to both of the first and second chip stacks.
Abstract:
A package substrate includes a substrate body and a plurality of patterns disposed on the substrate body. The substrate body has a first region including a chip attachment region and a second region adjacent to the first region. The plurality of patterns are disposed on the substrate body in the second region. Each of the plurality of patterns extends in a first direction to have a stripe shape, and the plurality of patterns are spaced apart from each other in a second direction which is substantially perpendicular to the first direction. Related fabrication methods, electronic systems and memory cards are also provided.
