Abstract
Is there a minimum energy required to compute a bit of information? Does the choice of state variable used to represent information affect the energy dissipated in computation? These questions are taking on more than mere academic importance, as evidenced by the heat produced by modern laptop computers. In CMOS logic the energy used to represent the bit of information is dissipated to heat at each logic transition. This way of processing information is very wasteful of energy and does not scale well as devices shrink to nanoscale dimensions. How low can dissipation be pushed? This presentation will examine the fundamental issues involved in computation, including the Landauer Principle and the use of charge as a state variable. Experimental results testing theoretical predictions will be presented. Will new device paradigms be required to achieve ultra-low power computation? An examination of the device requirements will be presented, along with preliminary experimental results, and a discussion of possible paths beyond Moore?s Law.
