memrister finally discovered
« on: May 01, 2008, 07:30:06 PM »
The memrister is the fourth fundamental electronic device, next to resistors, capacitors, and inductors. What is it good for? Memory storage that doesn't erase when the power is turned off.

Apparently the discovery was an accident by researchers at Hewlett-Packard.

Say goodbye to 1s and 0s and hello to a plethora of values.  Analog computers here we come.  Wahoo!

I think the ramifications are good by boot times, hello instant on computers, and hello cheaper FPGA like devices.

wow thats amazing!
Check out the Roboduino, Arduino-compatible board!

Apparently there's been a lot of "fightin' words" over this announcement lately . . .

From the article:
Quote
There is nothing new or revolutionary here. Bulk resistance versus incremental resistance is well known. Nonlinear resistances are well known. Resistance which varies depending upon the history of the device are well known. The claim that a fundamentally new circuit element has been found is overblown.

And I thought this was a neat quote:
Quote
HP Labs maintains that because of this property, massive memristor arrays could enable brain-like learning.

    In the brain, a synapse is strengthened whenever current flows through it, similar to the way resistance is lowered by flowing current through a memristor. Such neural networks could learn to adapt by allowing current to flow in either direction as needed.
