They already did.. and it is called VISTA.

It's not storing using a magnetic field. It's storing using the position of a few -missing- atoms of oxygen. The device is a two-layer sandwich of titanium dioxide films between two more layers of conductors (wires).
One of the two layers has a few missing oxygen atoms, forming "holes".
A flux of current in the wire adjacent to the layer with the holes will push the holes to the other layer.
Whichever of the two layers has the holes has one-thousandth the resistance of the other layer. Once the holes are in one layer, they will stay there, persistently, without power applied, until moved to the other layer with a slight flux of current in the proper wire.
The thing basically has two stable states - either one layer or the other has the holes.
The intermediate states, with some of the holes in each layer, cannot be accurately and repeatably obtained. So, like a common light switch on the wall, it's a two-state device for practical purposes.
Though what point you were making I will acknowledge I missed, so my reply above might not be relevant to your point. Sorry if that's so.

Think of how the transistor array became what is our new economic basis. The memristor array will be much more of an extension of mans imagination. Code will become dynamic and intimately personalised. You will be your array. This is ultimate security and ultimate control. There is no turning back. Bwahahahahaha....:)

You're leaping across a couple layers ... such conclusions are at best analogies.

More profit in it this way, with patents and all. Cleverness beyond the science.

Assuming arrays of these components will have dynamic effects, don’t you think you may be a little early in your countenance? This may be able to be made into a dynamic decision determinator. This can be used as a final determinant.

Re:
But in a memory resistor, the hose remembers what direction the water (or current) is flowing from, and it expands in that direction to improve the flow. If water or current flows from the other direction, the hose shrinks. If water or current flows from the other direction, the hose shrinks... Gadzooks, don't like the sound of that!

Well, it’s not exactly like a leaky diode. From what I am reading anyway. A “leaky” diode won’t change it’s properties, it’ll always be leaky.

You sound knowledgeable on the subject. If there was such a need for this device, couldn’t it have been simulated with a circuit containing active devices?

VISTAI just read that sales are going so bad for VISTA and so good for XP, that MS is going to stop selling XP soon (I don't remember when) to try to force people to buy VISTA.

This device is used to construct diode logic arrays. A ROM could be constructed with diodes before, but those aren't efficient. This device is capable of being reconfigured, so it's a read/write device, and the characteristics of the diode apparently allow for efficiency. That efficiency allows for large scale integrations that weren't possible with normal diodes. Diodes are a passive device...
"couldnt it have been simulated with a circuit containing active devices?"
Memory constructed with active devices usually requires some sort of power source, like a battery, to maintain the logic state of the gate array. Memory sticks and cards don't though. In those devices and in these, there's a capacitance present in each element of the array that holds the logic state of each gate. The key features of these devices is a nanoscale device with an ionic capacitance which allows for the creation of an electronic diode. The sticks and cards with active devices have larger scale elements and a capacitor associated with each active element to hold the logic state of the gate.

So this is a true passive memory element, neat. Long road from a laberatory device to a commercial product though.

I have no clue what you're talking about, but meanwhile here's a bunny rabbit with two pancakes on its head.
(
pancake inflation, I guess ...)

Thaaaaank you. That article gives me much more information.
They’re right — this is something fundamentally new, new, new. Very exciting stuff, this device.
The dual nature of the action (ie, push the current hard & fast, you have a digital response, slow and easy, you have an analog response) has very interesting possibilities.

Well, logically, yes. Just as the engine in my modest car could be simulated with 100 horses. Though I still haven't figured out how to get 100 horses to go faster than 10 or 20 miles per hour, and they seem to want to eat even when I'm not driving anywhere.
... and they wouldn't all fit under the hood of that little car.
