A method is described for identifying related pages among a plurality of pages in a linked database such as the World Wide Web. A coating having a low coefficient of friction is disposed on at least part of the proximal portion and the distal portion of the mandrel, where a part of the proximal portion and distal portion of the mandrel without the coating indicates a marking on the wire guide. The strapping cells provide a P+ strap between N+ active areas of two memory cells in a column and provide an N+ strap between P+ active areas of two memory cells in a column of the memory array.
