A three dimensional stacked nonvolatile semiconductor memory according to an example of the present invention includes a memory cell array comprised of first and second blocks disposed side by side in a first direction, and a driver disposed on one end of the memory cell array in a second direction orthogonal to the first direction. A light source is optically coupled to a tissue region potentially containing the contrast-labeled target tissue. By including three or more conducting layers, the diameter of the input device may be minimized. 01 to 10 parts by weight of at least one compound selected from the group consisting of benzotriazole-, triazine- and hydroxylamine-based compounds; the molded article thereof; and the method for controlling biodegradation rate using the same composition. Thus, a molded product of the magnetic refrigeration material is produced. Markers can also be pressed onto the stent by placing the stent in the gap and rotating the stent about its central axis.
