We investigate the use of endohedral fullerenes and 6-(Ferrocenyl) hexanethiol cation as
molecular non-volatile memory devices. We demonstrate stable encoding of the information
in the geometry and dipole moment of these molecules. The write operation can be
performed with external programming electric fields that drive the switching of the molecule

We investigate the use of endohedral fullerenes and 6-(Ferrocenyl)hexanethiol cation as molecular non-volatile memory devices. We demonstrate stable encoding of the information in the geometry and dipole moment of these molecules. The write operation can be performed with external programming electric fields that drive the switching of the molecule conformation. The read operation can be performed by reading the dipole moment through the generated electric fields. Moreover, the dipole moment encoding enables the integration of proposed memories with molecular Field-Coupled Nanocomputing logic. The capability to realize compatible and purely molecular memory and logic devices paves the way for molecular MemComputing, with new possibilities for nanoscale computing paradigms.
