A semiconductor device includes a substrate having a semiconductor element mounted thereon, and a heat sink. The composition used in the method of the present invention can be efficiently utilized for the wound healing, since p43, an effective ingredient of the composition, has an excellent effect on the wound healing by its action including the induction of macrophagemonocyte and endothelial cell re-epithelization, proliferation of fibroblasts or angiogenesis. The automatic white balance mechanism also determines gain adjustments based on the evaluating the average RGB values to achieve white balance. A backing layer is disposed in overlying relation to the substrate layer to hold the loop forming yarns in place. The minimum and intermediate gain values, may be selected by varying the physical characteristics of the current steering transistors which may be BJTs or FETs. According to one aspect of the present invention, a method for determining an average number of times each block of a number of blocks within a non-volatile memory of a memory system has been erased includes obtaining an erase count for each block that indicates a number of times each block has been erased.
