Despite what seems to be fast-paced progress from the outside, much of the tech world moves at a rather slow pace. Take for example data storage technologies. We are, to some extent, getting more storage, sometimes in smaller spaces, but we're basically just lumping more of the same thing. Eventually, the laws of physics will take over and we can no longer expand. Resistive RAM, or ReRAM or RRAM, wants to take take things to the next level by replacing the age-old NAND tech by something completely different.
