Samsung has shrinked the memory a lot still maintaining the specification of the DDR3 unaltered it is a great achievement, this will lead towards packing more memory in the same formfactor.

I'm blowing the EIQ trumpet, but check out http://www.electroiq.com/index/Semiconductors/sst-blogs/chipworks-blog-display/blogs/sst-blogs/chipworks/post987_3596488420747370540.html for plan-view images and more discussion.

Why Samsung did not follow the existing naming guidelines? They are trying to create confusion by coming up with their own naming convention. I guess all the chip manufacturers should also append to letters to their naming convention 1) AA - Above world wide average 2) BA - Below world wide average. This will give clear picture if the shrink is real or just hypothetical.

I think they sell the top-level images. You might want to contact the authors directly.

Interestingly, this can also be considered equivalent to a 4F^2 cell with F=46 nm. I wonder if they could not directly pattern at the 38 nm 6F^2 design rule. Still, they could have done something like 42 nm and still get cost advantage.

Using F=30 nm, this is a 9.4 F^2 cell area.

Is there a top view available for the cells?
