The filed of molecular electronics has seen an outburst of interest particularly motivated by the possibility of developing and characterizing the individual molecules to perform functions in electronic circuitry as performed by semiconductor devices[1-3]. Towards this goal, we have developed a molecular memory device that includes novel immobilization method for ferredoxin on gold surface. A recombinant protein with cysteine residue by using Polymerase Chain Reaction (PCR) was designed and then directly immobilized on Au surface without any chemical linker. The immobilization of the functionalized protein is confirmed by Surface Plasmon Resonance (SPR) and its surface morphology is analyzed by Scanning Tunneling Microscopy (STM). The memory function of self assembled ferredoxin was investigated by its redox properties of metalloprotein using Cyclic voltammetry, Chronoamperometry and Open Circuit Potential Amperometry (OCPA).The approaches outlined here can be applied for the development
of the molecular memory device
