A channel adaptor is provided which can be shared by a plurality of operating systems running in a data processing system, by generating an address translation table without changing inputoutput process control data. The main pole includes a top magnetic layer and a soft magnetic underlayer separated by a nonmagnetic spacer. The card data corresponds to financial accounts. An identification key is generated and the first configuration of the programmable hardware is used to encrypt the identification key. After formation of a node dielectric on sidewalls of the second trench, a conductive material is deposited to fill the trenches, thereby forming a conductive trench fill portion and an inner electrode, respectively.
