Memristor built by researchers from HP

Thirty-seven years later, a group of scientists from HP Labs has finally built real working memristors, thus adding a fourth basic circuit element to electrical circuit theory, one that will join the three better-known ones: the capacitor, resistor and the inductor.

In 1971, a young circuit designer (...) Leon Chua (...) realised something was missing. He was toying with the non-linear mathematics that describes how the four variables in a circuit – voltage, current, charge and flux – behave in the three basic elements.

The three building blocks each relate two of the four electronic properties of circuits, creating a chain linking charge to flux via voltage and current. But his calculations showed there should be a fourth device to directly link flux and charge.

Do you forsee any impact on the graphic chipsets/cards? I can clearly see advantages in the storage space, but it's hard for me to speculate on the impact on e.g. rendering pipeline...

I'm still waiting for the transcapacitor...

I'm still waiting for the transcapacitor...

blast you, it's called a flux capacitor. And when this baby hits eighty-eight miles per hour... you're going to see some serious s**t.

the most interesting characteristic of a memristor device is that it remembers the amount of charge that flows through it.

hm........

think about fabricating a new type of non-volatile random access memory (RAM) – or memory chips that don't forget what power state they were in when a computer is shut off.

double hmm........


Isn't there a big problem of well... I don't know........ changing the direction of current to then change the corresponding resistance. Or even adjusting the amount of current in a single direction. :|
