<P>This article reviews the current status and future prospects for the use of nanomaterials and devices in memory technology. First, the status and continuing scaling trends of the flash memory are discussed. Then, a detailed discussion on technologies trying to replace flash in the near-term is provided. This includes phase change random access memory, Fe random access memory and magnetic random access memory. The long-term nanotechnology prospects for memory devices include carbon-nanotube-based memory, molecular electronics and memristors based on resistive materials such as TiO<SUB>2</SUB>. </P>
Electrical Conductance in Biological Molecules
Waleed Shinwari, M.,Jamal Deen, M.,Starikov, Evgeni B.,Cuniberti, Gianaurelio WILEY-VCH Verlag 2010 Advanced Functional Materials Vol.20 No.12
<P>Nucleic acids and proteins are not only biologically important polymers. They have recently been recognized as novel functional materials surpassing conventional materials in many aspects. Although Herculean efforts have been undertaken to unravel fine functioning mechanisms of the biopolymers in question, there is still much more to be done. Here the topic of biomolecular charge transport is presented with a particular focus on charge transfer/transport in DNA and protein molecules. The experimentally revealed details, as well as the presently available theories, of charge transfer/transport along these biopolymers are critically reviewed and analyzed. A summary of the active research in this field is also given, along with a number of practical recommendations.</P> <B>Graphic Abstract</B> <P>Biomolecular charge transport is presented, with a particular focus on charge transfer/transport in DNA and protein molecules.
