There has been a recent breakthrough in organic memristors, indicating that we may see the adoption of this technology in the not too distant future. The problems with previously developed memristors were that they were too slow to change states and unable to hold the memory of that state for long enough to be useful. This new type of memristor can switch states in 30ns or less, comparable to traditional resistors and it is capable of holding that state for over 11.5 days without any power. This memristor is also quite stable, with an expected lifetime of 10^12 cycles. One of the driving forces behind the development of a memristor which can perform as well as a traditional resistor is cost, memristors are much less expensive to make and do not require rare metals in their manufacture.

"Researchers in Singapore, the US and India have now made a new organic memristor based on ruthenium complexed with azo-aromatic ligands that is better than any such memory device made to date."
