iPhone NAND Flash LGA-52 to Micro SD?

I am curious...

Is it possible to take the NAND Flash LGA-52 pinout and take that into a Micro SD card?

From there any system would not know the difference as it would look like a normal NAND Flash chip with data to read/write?

I know it cant possibly be that simple but I have to wonder if it might be!?

I don't want to be optimistic but could it work fairly simply?

Thank you in advance! Would love to know is this could even work.

The main difference between the NAND chip in you phone and a microSD card is that the microSD card is a monolithic design. That means that the controller and actual memory are all on the same semiconductor wafer. The microSD card is recognized by your computer because it goes through the Flash Translation Layer of the controller. Whereas the NAND chip on your phone is just that...a NAND chip. It is being written and read by the micro-controller, in this case the A6 processor.

That means you can't access the NAND without going through some kind of FTL. Here's an interesting write-up on data recovery of monolithic memory cards.

So what it not be possible to add a Nand Flash Controller after the Nand Flash LGA-52? Then that data be sent off to the MicroSD? Thank you for your quick response!


Well...yes. That's what engineers do when they design flash memory cards. However, it is not plug and play and parts aren't necessarily available off the shelf either. I focus more on the DR side of things so this is taking it beyond my full understanding. My initial point was just to point out the inherent difficulty in doing this. A great research project...certainly but not a quick "voila, now I have a memory card".

Are you doing this for data recovery or as a project?


A project! Your insight has been very helpful. Thank you! I have been researching this and you have finally given the answer I need.
