The RAM you were referring to in your first post is a different part in the iNAND range. You can get iNAND MCPs which have multiple individual chips all in a single package.

Cool, I began investigating this because I wanted an SD-card slot in my kindle. Given that the iNAND is just SD-interfaced data storage chip, the SD-card slot could probably replace the chip.

[QUESTION]: Is it necessary to have a write-distribution system in between the processor and the SD-card to level the wear on the SD-card, or is the wear-leveling built into the processor or the SD-card itself?

I have found a datasheet (SanDisk iNAND), similar to the one found in my Kindle, but it's not the same. Pin arrangements look alike. I don't know if the SanDisk iNAND chip is pin-compatible with the Samsung chip you all seem to have. But here it is in any case, if someone wants to give this a shot before I do :) http://www.spezial.com/commercio/dat...DS_-_iNAND.pdf

If I manage to do it, I'll document every step of it. Source code modifications will also be released. Please do the same.
