1. A semiconductor device comprising:
- a first driving circuit region and a second driving circuit region on a first substrate to generate driving signals;
a second substrate on the first and second driving circuit regions;
a memory cell array region on the second substrate, the memory cell array region entirely overlapping the first driving circuit region and not or partially overlapping the second driving circuit region;
a first upper interconnection layer on the memory cell array region; and
a first vertical contact through the memory cell array region and the second substrate, the first vertical contact connecting the first upper interconnection layer to the first driving circuit region.
