A semiconductor package may be composed of a variety of different types of semiconductor chips of different sizes and support structures stacked within the semiconductor package. Semiconductor chips having a larger chip size may be stacked above smaller semiconductor chips. Smaller chips may be included in a layer of the semiconductor package along with a support structure which may assist supporting upper semiconductor chips, such as during a wire bonding process connecting bonding wires to chip pads of the semiconductor chips above the support structure. Use of different thicknesses of die attach film may allow for a further reduction in height of the semiconductor package. When implemented as a package housing a memory controller, DRAM semiconductor chips and non-volatile memory chips, locating the memory controller in a lower layer of the semiconductor package facilitates usage of the package substrate as a redistribution layer to provide communications between the memory controller and the DRAM and non-volatile memory chips.
