Pretty exciting, but not nearly as awesome as
memristors.
If you don't feel like reading the entire article on Wikipedia, memristors can hold information without using a charge. From this, we will soon have chips which produce little to no heat when used. We will have computers which do not need to power down/up; they will instantly turn on/off. Because of the way in which they hold information, the bit will vanish; a single part of it will, instead of holding a value of 0 or 1, be able to hold many more values, perhaps one part could hold an entire byte; 256. That's 128x more space in the computer, so a computer with 100 gigabytes of space would now have around 13 terabytes. Of course, that may not be the limit, for all I know a single part could hold 2 bytes, or 3, or maybe 4. But that's not all. Memristors are far easier to stack on top of each other, allowing for denser packed circuits. There's even more space to add to your computer. They also function as fast as RAM, so games and such would never need to "load up" (get information from the hard drive and place it into the RAM for faster access) again; you just click and play. And of course, with the entire hard drive then becoming so easy to access, games could become
much larger in size and depth without any decrease in performance. What I mean is, a single level or area in a game would normally take up a certain amount of the RAM, but with the entire hard drive being just as good, a level could be hundreds of times larger, and as long as you don't try to draw the entire thing to the screen all at once, there won't be any decrease in performance. Of course, if memristors are put into graphics processors as well, then you could draw the most complicated map you can think of to the screen without a significant change in speed as well. Games where, after you beat a level, you load the next map and remove the other from RAM will be a thing of the past. By the time you finish clicking through the game menu everything will already be loaded and ready.
Since the way the memristor's memory works is that, when a charge is put through it, its resistance changes, this means that the more often a memristor gets a certain response, the greater/more noticeable the difference in resistance. In other words, memristors are the future for AI. So a while in the future we may also be getting robots with memristor brains.
Sorry, didn't mean to rant, but memristors get me so excited
I can't wait until they are implemented into computers more. Note that a good deal of what I said was me hypothesizing, such as the game loading speed and storage capacity of memristors, but they are all entirely possible.
