The internal memory is NAND, which is the same technology used in an SD card, but it's in a BGA. It would take some skillfull soldering to pull that off. Not to mention, the memory is of lower fault tolerance than SD. Replacing it with anything but similar memory would kill the lifespan of your system.
It is possible, but it's not cheap or worth it.
You're much better off getting multiple 2GB SD cards.

But they had to put it on a switch, and could only use one bank at a time... one bank was running the latest firmware, and the second bank was running an older firmware... but the Wii can only see 512 at this time... no matter how much you throw in, it'll only see and use 512Mbytes.
Arakon said:2 issues: more memory may need an extra pin, which very likely is not connected on the wii. second: the wii firmware doesn't attempt to address any more than the 512 MB.
and nintendo does not have larger nands either.
