When first asked, the developers of the Pandora stated, that more than 128MB Ram is not possible, because there is no Omap 3 with more than 128MB. Now it seems they use an external RAM chip. And here comes the problem: In the n810 they only provided one minisd because of the gps chip and antenna. In the NITs free space is rare.

RAM and NAND aren't integrated with the SoC. At least with the Pandora and the Beagle Board, they're in what's called a PoP (Package-on-Package), which is a chip that rests on top of the OMAP3 and sandwiches it between itself and the board. The problem is that 6 months ago, there weren't any 256MB RAM PoPs available, now a few months ago 256MB RAM PoPs showed up, so the Beagle and Pandora are going to ship them (though the Beagle's will be slightly faster and contain no NAND).

Yes, it'd be perfectly reasonable for Nokia to swap out this chip with no impact on size.

Where I come from, swap is usually 1.5x the RAM, which would lead to 512MB. Either way, there's no way they'd ship 384MB of RAM.

The other proposal is that it's enough to support a suspend to disk.
