The HP Memristor Debate 62
New submitter AaronLS writes "There has been a debate about whether HP has or has not developed a memristor. Since it's something fairly different from existing technologies, and similar in many ways to a memristor, I think they felt comfortable using the term. However, the company has been criticized for using that labeling by former U.S. patent officer Blaise Moutett. On the other hand, had HP created a new, unique label, they would have probably gotten flack for pretending it's something new when it's not. Will anything positive come from this debate? Electrical engineering analyst Martin Reynolds sums it up nicely: 'Is Stan Williams being sloppy by calling it a "memristor"? Yeah, he is. Is Blaise Moutett being pedantic in saying it is not a "memristor"? Yeah, he is. [...] At the end of day, it doesn't matter how it works as long as it gives us the ability to build devices with really high density storage.'"

For those like me that went huh?
The memristor ( /mmrstr/; a portmanteau of "memory resistor") was originally envisioned in 1971 by circuit theorist Leon Chua as a missing non-linear passive two-terminal electrical component relating electric charge and magnetic flux linkage. More recently the memristor definition was generalized by Leon Chua to cover all forms of 2-terminal non-volatile memory devices based on resistance switching effects. http://en.wikipedia.org/wiki/Memristor [wikipedia.org]
Personally, I still have no idea.
What gives? As long as it's close enough... (Score:5, Insightful)
'They' say it isn't a true memristor because its data deteriorates a bit over time. But ... isn't that true of all other current basic electronic components as well? Capacitors have some leakage, making it a 'bit' a resistor. Inductors do not have a perfect Q. Even at its resonance point some energy is dissipated as heat, dampening the resonance circuit it is part of and making it a 'bit' a resistor as well. Resistors are most of the time at least 'half' a winding on a 'coil'... when alternating current passes through them with a high frequency, they act a 'bit' as an inductor. And they may have a parasitic capacitance with other components near it.
So, what gives if this HP invention is not the 'perfect' memristor. As long as it's close enough, it would do. In other words: if it quacks like a duck...

Let's keep scientific terminology pure, and not let the business types hijack all our established terms for their marketing bullshit.
