Abstract
A stacked semiconductor memory device comprises a semiconductor substrate having a functional circuit, a plurality of memory cell array layers, and at least one connection layer. The memory cell array layers are stacked above the semiconductor substrate. The connection layers are stacked above the semiconductor substrate independent of the memory cell array layers. The connection layers electrically connect memory cell selecting lines arranged on the memory cell array layers to the functional circuit.
