Memristors are now being commercialised

And so with HPs announcement of ReRAM we have entered the next phase of Memristor technology, Commercialization! This should lead to cheaper and faster memory for all our device needs.

Memristors or resistors with memory are 10 times faster and uses 10 times less power than Flash memory chips commonly used in portable digital devices. The device also has greater memory storage and requires less space making it ideal as memory chips and even hard drives.

I'm looking forward to these coming out in 2013.
