https://images.anandtech.com/doci/16252/M1_575px.png This states 8 channels but teardowns have shown that there are only 2 memory chips so I'm not sure exactly what's going on.


LPDDR4x can have multiple dies per chip.

Based on your discussion point, then I'm thinking x16 per channel, 4-dies per chip, 2-chips for a total of 8-dies for the 8-memory controllers.


But is there a standard pinout with that many data pins?

Hmm... I don't know what's going on.

This chip claims to be LPDDR4x, but it is a 556-pin package. This is in contrast to your earlier data-sheet, which only has 200-pins. Maybe LPDDR4x doesn't have any standardized pinouts?

This isn't exactly where I normally work, so I'm not entirely sure what is going on.


Most likely, it's two DRAM dies per package. Those DRAM packages look ridiculously wide, so the DRAM dies might not even be stacked.
