Memristor
Anyone read the latest IEEE Spectrum, 12/08 on the memristor? Fascinating article.
Will revolutionize memory, and save power. If I had a web link I would attach; anyone who might have a web account may be able to help.
Essentially, you can program a "device" to a certain resistance, depending on the voltage magnitude and/or time applied. Once this resistance is obtained, it remains permanently. The composition is titanium dioxide coupled to a layer of oxygen depleted TiO2. The oxygen freely moves its concentration through this interface by means of applied voltage. The boundary essentially moves, and as it does, the total conductivity of the material is changed.
