Researchers at HP Labs and Princeton University have come up with a new non-volatile write-once memory material which is made out of plastic rather than conventional silicon. The new memory is jolly low power, cheap to make and potentially high capacity.

‘The new memory, which could end up in a small format similar to CompactFlash or SD Cards, doesn’t use transistors to store information. Instead, bits are written when a strong current passes through a polymer fuse, causing it to blow and change its conductivity.’
