Double-floating-gate Field Effect Transistor memory that is storage and memory. It will boot from the "working" image very quickly. It incorporates both volatile and non-volatile memory. This allows It to act as memory and storage in a combined package. Really a couple of terabyte should do it for RasPi revision #47

Last time this came up I remember that Liz said this was a mistake by Element 14 and that someone had added a placeholder for a non-existent product. I would not be surprised to find this is some sort of similar glitch. I wonder if their contract with the Foundation even allows them to make such a product.

Seems like they have 5,288 in stock - but you can't actually order one as it won't let you add one to your basket. :)

Just to fan the flames a bit ... I'm pretty sure thatI saw a comment recently by someone who heard Eben imply (perhaps at recent maker fair in USA) that 512MB is coming soon.

search for "zram swap" on the forums and make a 64MB compressed swap ram disk. This will make the stall to swap more gradual, and not a sudden crawl. It will make a 32MB window of slight slowness earlier, and a 32MB window of not as slow as full on thrashing. This gives about a 64MB window of gradual decline into swapping to swap disk.

Also due to the way swap paging works, the critical page set for any application is usually quite small. It can be reduced further at compile time with profiling and a super flashy linker which is not yet available (it could place common use code in same paging block, and cache lines). And al optimization in the distro needs to be done for small size, as with good caching this is often the highest speed setting too, for large stuff.

It's way too early in the prototyping stage to make a 512MB version, as this would move development away from making the best of 256MB.

News just in: RASPBERRY PI 512mb IS OUT IN THE WILD!!!
I ordered a Pi a week ago and I received it today, I got a paper stating 'RASPBERRY PI WITH 512 MB RAM, Thank You For Your Order, We have a little surprise for you, Inside the box is a new Rasberry Pi with 512MB RAM waiting for you!. Faster... Double RAM... Same Price...'

Yes I did not pay extra also, I will be uploading images soon, as I'm in the office right now!

I dont know if this is a joke or not, maybe you guys will be able to help
http://www.element14.com/community/mess ... rt=0#61875

Say this on the Element14 forum and thought this could be fake. Lets just wait and see.

EDIT: I just check the E14 site, they do not sell the raspberry pi with 256mb RAM only selling 512mb!

this is exactly like the rev2 board. Out in the wild without any notice.

err, no there should be three, so they should be named Kwik Kwek and Kwak (or for non Dutch speakers Huey, Dewey, and Louie, or whatever these ducks are called where you live) :mrgreen:

That part number is not available at Newark/Element 14. I suppose the U.S. will get them last just like everything else. I hope this is true. I will have to buy at least one.

To order it off Newark, I had to go to the E14 community, there is a link advertising the new larger memory pi on the landing page for the pi community. I'm uncertain as to when the Newark page will contain a link to purchase the larger pi.

Here's a direct link for US peps
