A memory system package is provided by placing memory chips face-to-face using as an interposer a thin flexible carrier having through-carrier-connections, vias, for common memory chip I/O pads which are brought out to access external signals, either control, I/O or power. These external signals may also be wired to memory chip pads that are not common.
