Molecular memory

[s]tores data using a protein called bacteriorhodopsin. A laser can change the protein for bR (0 state) to Q (1 state), which makes it an ideal AND data storage gate, or flip-flop. Molecular memory is inexpensive to produce and can operate over a wider range of temperatures than semiconductor memory. A molecule changes states within microseconds; the combined steps to read or write operation take about 10 milliseconds. That might seem slow. However, like holographic storage, this device obtains data pages in parallel, so a 10 Mbps throughput speed is possible.[1]
