SanDisk 32GB microSDHC - Stack of 8 4GB die

Mostly, I'm sharing this story because of the cool photo that Wired's GadgetLab included.  The basic news is that SanDisk has announced a 32 GByte microSDHC card.  They used a 32 nm process (cool symmetry — 32 billion bytes and 32 billionths of a meter) and arranged the die in an 8 high stack of 4 GB die.  Apparently the suggested retail price is around US$200.

Here's the photo that Wired included:

32nm X3 chip under an electron microscope that shows eight-die stack.  This is an actual photo of a 32nm X3 card that was torn apart to show the layers of memory chips inside.

Exciting stuff!

Note:  The original image from Wired wouldn't display properly in IE, so I cached a version that IE could handle.  The original is here.  The full size cached version is here.
