Hi all, I came across this article about a Swedish company called Opticom while doing memory research. Evidently, for the cost of a few cents, a they can "produce a memory module with a capacity of up to 170,000 gigabytes, which could fit on a bank card." It is not my area of study, so I offer it here to those of you who are studying material memory. Here is an excerpt:
"The principle of organic memory is as simple as it is brilliant. A polymer film which is contacted by a passive matrix, emits light onto the memory medium - a protein film. The light causes the proteins to switch between two stable states. The states can be distinguished above all by those colors which they absorb and those which they let pass. Once they have been changed, the states remain stable even without light. The data is then read with less intense light, that doesn't change the memory content. In one state the proteins absorb more light, in the other less. Another polymer layer, also matrix-regulated, acts as a photo-detector and measures the light which has been diffracted by the proteins."
It's a long article. Here is the link. http://www.cwu.edu/~borisk/312/018.html
