In one embodiment, an apparatus comprises serializerdeserializer circuits. The method for fabricating the nonvolatile memory device comprises providing a substrate. The handle may include a shank rotatably and foldably secured to a lower segment. An alkyl group is appended to the 5 position. An excitation line is arranged such with respect to the three sensor element arrangements that when impressing a predetermined current into the excitation line respective predetermined calibration field components with respect to the spatial axes in the sensor element arrangements are generated. A predetermined data set is written into the memory module after the operating voltage of the memory module is adjusted, and the written data set is read out from the memory module, to accomplish a data writing and reading process of the memory module.
