Emerging technologies on silicon

Moore\´s law and its mapping into the ITRS have been the most powerful drivers of the progress in microelectronics in the last decades. This paper discusses possible futures while approaching the "end-of-the-roadmap". We discuss long term evolutionary paths as well as some more disruptive approaches of the different building blocks of an information processing system - namely the processing unit, memory, interface and communication, and the interconnection of these elements -, taking into account some of the expected fundamental and practical limits. An enhanced progress is expected from a synergetic development of the building blocks and of the system architecture, with some exploratory paths departing from the present way of thinking, e.g. through bio-inspired architectures.
