Molecular Electronics based memories

UCLA and the California NanoSystems Institute are reporting on rapid progress in Molecular Electronics based on rotaxanes and catenanes [1, 2].

They apparently have an operational 64-bit RAM and are working on a 16-Kbit memory. These have densities that conventional DRAM or disk drive manufacturers can only wish for in their dreams.
