  • CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.
  • We hope the site problems here are now solved, however, if you still have any issues, please start a ticket in Contact Us

Anyone here interested in CompSci?

If so, what's your opinion on the sudden run of announcements dealing with memristors? By my count, we now have two companies claiming to have functional memristors, one temperature based, the other a titanium oxide composite.

For anyone who doesn't know, a memristor is a type of fundamental electronic component that increases in resistance flows in one direction, reduces in resistance when current flows the other direction, and if the current stops, it maintains it's previous resistance indefinately. HP is touting it as simple to manufacture using existing lithographic techniques, and is claiming to be releasing memristor based devices within the next couple years (flash memory devices first).

Some advances from this new tech: High RAS stable memory, in other words, computer ram that, if power is interrupted, will retain it's previous state, allowing for an elimination of lost data due to power interruption, and instant on systems. More powerful processors without reducing transistor size, 1 memristor can replace up to 5 components in standard linear circuits, giving moore's law an instant turbocharge. solid-state neural networks, a fundamental component with inherent memetic capacity is critical to creating functional solidstate nodes capable of real world applications and provide the capacity for reconfigurability.

I've been hyped over this tech for weeks. :)

what kind?

I work with making test equipment for testing MR Heads that go in the Hard Drives.

Right now I've got a programmable tester I'm developing that will allow the testing of wafers +/- 1K Oe in about 1 Oe Steps, while driving it with either a Consent Current or Consent Voltage Source.

This allows about 1K Samples to be taken every second.

Very cool. I'm still in college, but I'm very keenly interested in neural networks and AI, and going from virtualization to hardware systems for neural networks will have a multi-fold increase in speed. The biggest problem is going to be bus architecture inside the chip. Unless the chip is purpose-built, then the dynamics of a neuralnetwork will require an exponential increase in connections every time a node is added, a shared communication channel between nodes can be established, but then you run into the problem of having to synchronize the nodes instead of having the sucker be truly asynchronous. It'd also induce buffer limits which could slow down the neural net.

Personally, I suspect they're a little over-hyped. They don't seem to do anything fundamentally new, just offer potential speed and density advantages in the long term.

Non-volatile memory is nice... it will reduce power drain in laptop sleep mode.

Speaking with one degree in electronics already, a 4th fundamental component is really big news.

resistor
capacitor
inductor(coil)
memristor

These are the 4 basic components, every other component that exists is just a variation on one of these 4. The 4th recent addition will revolutionize electronics in the same way the transistor did so. I don't think the inventors of the first transistor ever envisioned what fundamental it's changes to our technology and society would be.

Indeed, cynics would have said about the transistor "it's just like a valve," but they would have been wrong. The real revolution came from being to pack so many in a small space.

The memristor may also have spinoffs... I guess we'll see.
