An electronic device may include a temperature sensing semiconductor substrate, that may include a thermal sensor at an upper surface thereof, and a cooling semiconductor substrate having an upper surface coupled to a lower surface of the temperature sensing semiconductor substrate. Six signals and their complements are sufficient to control the sorting circuit for both the read and the write operations, and provide both the DDR and the DDR2 functionality. Thus, the present invention advantageously provides commercial qualities and quantities of doped semiconductor films from a doped \u201cliquid silicon\u201d composition.
