Sheet/DRAM/Mobile DRAM/Low-Power 
DRAM/LPDDR/70-series/T79M_2Gb_mobile_lpddr_sdram.pdf
seems to fit.

ToDo: ask if micron can certify it for DM3730.

I don't get it :-S
a) I missed the huge "2Gb" in that datasheet
b) the chip "MT46H256M32L4JV-5 IT" is announced as 
"density 8Gb"

When sourcing MOQ:1000, will we be able to get a dozen of those cut 
from tape and packaged in separate moisture protection bags?
We don't want to open the 1000-bag and start the 72h period to 
solder those 1000 once they got exposed to environment

Comment 4 by Nikolaus Schaller, Dec 3, 2013

Not a big issue. Chips not used can be resealed. And if they are 
stored for let's say 1 year they will be "baked" i.e. 
dried at 120C for 24 hours and can be soldered like new ones. Well, 
we loose the warranty by the manufacturer but in the GTA04 project 
we did not see any issues that could be traced back to that 
procedure. It may become relevant when increasing yield from 99% to 
99,1% - which is 1k less failures if we produce 1 Mio units.

for baking we also lose the tape iiuc. Needs repackaging to trays.

Comment 6 by Nikolaus Schaller, Dec 3, 2013

Micron memory chips, TI CPUs and UMTS modules already come in trays.

Spotted in a dead N9

So we CAN get N9 PoP (can we?)
