In an article published in the journal Nanotechnology, HP (NYSE:HPQ) unveils the latest version of its much talked about memristor.
The news this time is that the device shows great durability. In a laboratory setting HP has successfully rewritten data to a memristor more than a billion times by heating the memristor to about 300 C and then again cooling it off. The memrisor is made of titanium oxide and by heating it HP can create vacancies that will remain when the device cools off again.
The memristor is seen as a potential successor to both DRAM and flash combining the best attributes of both technologies.
The memrisotr is nonvolatile, which means that it will remember its state even when power is turned off. This is combined with the speed of DRAM and the fact that individual bits can be addressed; unlike flash where you have to write whole pages at a time.
HP is working with Hynix of Korea to manufacture devices, but a complete device is still a few years away.S|A
