Is there some trick I don't know about for reading Micron BGA-152 chips with NR/FE? I've tried reading @ 3.3v & 1.8v, also tried converting the 3.3v signals to 1.8v. Donor PCB's all use 1.8v.. There are always random groupings of uncorrectable bit errors.. |

NR is not so good for modern memory flash. Many many reading errors. |

I get same thing with Micron BGA-152 chips. PC3k, FE, and i even tried on VNR where you can control the various voltages but i get same results no matter which power scheme used. |

The BGA I read - with 2 different tools, had bit errors as well, spread over the dump though. |
