In some embodiments, a semiconductor device package assembly may include a first substrate. The semiconductor device package assembly may include a first die electrically connected to the first substrate such that the first die is directly bonded to the first substrate. The semiconductor device package assembly may include a second substrate directly bonded to a surface of the first die. The semiconductor device package assembly may include an electronic memory module. The electronic memory module may be directly bonded to the second substrate. The semiconductor device package assembly may include a thermally conductive material directly applied to the electronic memory module. The semiconductor device package assembly may include a heat spreader directly bonded to the thermally conductive material. The heat spreader may function to transfer heat from the first die and the electronic memory module through the heat spreader from the first side to the second side.
