ABSTRACT:
A semiconductor device having an increased integration density. The semiconductor device includes a memory cell array, and a peripheral circuit region formed over the memory cell array and to be in electrical connection to the memory cell array for controlling the input/output of the data signals. A large part of a semiconductor chip area can therefore be used for the memory cell array, thereby increasing the integration density of the semiconductor device.
