Anyone ID one of these chips yet either in PC3K Flash or VNR? They are the ones used in the iPhone and are now being seen in a lot of flash drives.

I have had two so far. Both are from PNY's, one 64GB and one 128GB.
Controllers are pretty standard so if we can read the chip we should be good.
One: AM6998E
Second: PS2251

Thanks :-)

I did see these but one post is 6 months old and the other 3.
Just wondered if anything has changed.

go to flashboot or whatever, get the controller pinout (phison most likely would be there) and trace the pins from controller to nand chip.

put the continuity beep function on multmeter. put one probe on pin 1, the other test all nand pads on PCB. when you get a beep, map pin of controller to pad of nand. make a paper map, there are controller pinouts on I think Flashboot.ru or usbdev or something.
