It also says "IBM" very faintly, right above the letters "CPU," on the IC on the right. I've never heard of IBM fabbing ARM architecture CPUs, so...Traverse96 said:http://www.facebook.com/photo.php?pid=8339...150171505589409
Well, at least one of the CPU's is an ARM. I can't tell what anything else is, but so far, at least the CPU is an ARM.
...this is probably blasphemy, but maybe it's a very small, custom PowerPC with an ARM coprocessor like what is used on the Wii with Broadway/Starlet.
EDIT: after a closer look, seems like it says "1B44" or something along those lines and NOT IBM. Nintendo is such a tease. It's most likely just one or more ARM CPUs under the hood, pretty much the industry standard for a portable device such as the 3DS.
The Toshiba chip is most definitely NAND and/or DRAM, impossible to tell what model number it is. Not sure what the IC next to the CPU is. There are two of them on the board, one on the top and one on the bottom.
