Rugged molecules that remember

Porphyrin molecules created for data storage are remarkably hardy, holding up under the high temperatures and trillions of read-write cycles required of current silicon-based technology, says David F. Bocian, chemistry professor at the University of California, Riverside. Molecular computing, Bocian says, may supplement or replace semiconductor technology that, limited by the physics of silicon, is rapidly reaching its limit in terms of compactness and efficiency.
