The Holy Grail of this technology would be to use one molecule to store one bit. For the near future, it would be more realistic to expect to have systems that use large groups of molecules to represent a single bit. Different types of molecules have been researched, including protein molecules. A more precise name of a molecular memory system that uses protein molecules is Protein Memory.
Other types of molecular memory would have more precise names derived from the types of molecules on which the technologies are based. In the mid-1990s, the development of a protein-based memory system was the project of Robert Birge – chemistry professor and director of the W.M. Keck Center for Molecular Electronics. He was assisted by Jeff Stuart, a biochemist and one of Birge’s graduate students.
