Memristor Shows The Future Of PC’s
Back in 1971 Leon Chua, an engineering student studying non-linear circuits, made the assumption that a fourth basic circuit element (besides the the capacitor, resistor and the inductor) exists. He even went all the way to come up with its mathematical expression and its physical behaviour.
Now in HP Labs, scientists manage to create this new element, called memristor. This component can process information in the same manner that the human brain does. It works by remembering how much charge has gone through it and hence it can be used to make memory chips that do not loose their stored information when the PC is switched off.
By having a component whose resistance is increasing depending on how much current has passed through it, PC’s would be able to run not only on 1’s and 0’s but also in in between states, hence carrying more information.
The results from this work will be published in today’s edition of Nature.
