A non-volatile storage solution

2. Memristory – a brief history
The memristor was envisioned by circuit theorist Leon Chua in Chua claims the memristor is actually the oldest known circuit element with its effects predating the resistor, capacitor, and the inductor.
Generalized as a fourth electrical component, along with the resistor, capacitor, and the inductor.
Some researchers believe that human blood and skin should be classified as memristors.
It is currently being developed by HP, SK Hynix, and HRL Laboratories and could possibly be available commercially by the end of 2014.

3. It is essentially a resistor, which implements electrical resistance as a circuit element but with memory.
The memristor is a non-linear functional relationship between magnetic flux linkage.
Like an ordinary resistor, a memristor would create and maintain a safe flow of electrical current across a device.
Unlike a resistor, it “remembers” charges even when they lose power. Which allows for better information storage.
What is it?

4. How it works
Depending on the direction of current flow through the memristor circuit, the electrical resistance will either increase or decrease.
Memristors are nano devices that remember information permanently, switch in nanoseconds, are super dense, and power efficient. That makes memristors a potential replacement for DRAM, flash, and disk.
It is a thin double layer of titanium dioxide film placed between electrodes.

5. A memristor is a pipe that changes diameter with the amount and direction of water that flows through it. If water flows through this pipe in one direction, it expands (becoming less resistive). But send the water in the opposite direction and the pipe shrinks (becoming more resistive). Further, the memristor remembers its diameter when water last went through. Turn off the flow and the diameter of the pipe ”freezes” until the water is turned back on. That freezing property suits memristors brilliantly for computer memory. The ability to indefinitely store resistance values means that a memristor can be used as a nonvolatile memory.

6. Advantages
Memristors can retain memory states, and data, in power-off modes. Non-volatile random access memory, or NVRAM, is pretty much the first to-market memristor application we’ll be seeing.
It can be scaled down to sizes much smaller than currently available allowing designers to overcome modern Moore’s Law limitations. For example, nand flash has a minimum limit due to memory cell disturbance and other degradation during read and write operations. The thin film technology of the memristor changes the game by order of magnitude and actually improves performance as it is scaled downwards.
It is projected that we'll reach the end of our ability to scale RAM, flash, and disk in the next few years. Fortunately for us the memristor is here to save the day. Memristors have the power and speed of the DRAM cell and the (potential) lifetime of a hard disk. Currently the memristor has a lifetime greater than flash, but they are working to extend that. In five years memristors could completely replace DRAM and disk and eventually CDs and DVDs. It is a universal non-volatile memory. 

7. Advantages
The memristor is a new architecture that allows the stacking of multiple crossbar memories on top of each other. This allows multiple petabits of memory (1 petabit = 128TB) in one square centimeter of space. Consider 1 terabyte is equal to 128 DVDs or 250,000 4 Meg images. We are talking about a lot of power efficient storage in a very little space.
They can be used for logic -- they can be used as processors. This is very significant because instead of sending data to the processor and then back again, which takes time and energy, we could shuttle the processing code to the data -- which is smaller and quicker.
Using memristors for processing brings other potential changes. Instead of just two states, on or off, as with transistors, memristors can represent many states. This means we can create new types of computing models, we can also create analog computers, which you don't program, but you let them learn. You can then replicate the learning to other memristor analog computers.

8. Applications
In the near term, the most obvious application for memristor technology is as a replacement for Flash memory.  “Memristor memory chips promise to run at least ten times faster and use ten times less power than an equivalent Flash memory chip,”
Memristors can retain information even when the power is off and are highly energy efficient. This means that your laptop could boot up much faster and last longer on one charge since it consumes less energy.  Given the number and sophistication of apps running on smartphones, this should also significantly extend the usable time between charges.
Memristors fundamentally operate in a similar fashion as the biological synapses in the human brain. Another potential application of memristor technology would be an 'artificial synapse' in a circuit designed for analog computation.

9. Conclusion: Memristor = Cylons
