The device for processing signals may be designed as a transmitting and receiving arrangement or exclusively as a receiving arrangement, and has a baseband component and a radiofrequency component. According to one embodiment of the invention, the sheath wall is of a non-uniform thickness having a cylindrical outer surface and a polygonal inner surface. The flowcharting module allows active diagnosis objects to be associated with at least one of the action and decision blocks. The method also includes forming an oxide along a bottom of the active trench having a thickness greater than a thickness of an oxide along the first sidewall of the active trench. One end of the detachable member is detachably coupled to the connecting member, and the other end of the detachable member has a colloid part. The present invention groups and services the memory requests according to the property of 3-D pipelining.
