Is this statement true? In this die shot of the M1 Max the RAM appears to be integrated into the SoC https://images.anandtech.com/doci/17019/M1MAX.jpg https://

  What you're seeing there labelled LPDDR5 is the memory /controllers/, not the memory itself. The silicon area for the amount of DRAM we're talking about would dwarf the IC you're looking at -- and the 3 nm process that the logic is made on is not compatible with deep-well capacitors used for DRAM. There's a significant amount of SRAM on the chip (the SLC blocks, and many other cache blocks), but orders of magnitude less than the external DRAM we're discussing.

    Thank you for this information, exactly what I was looking for
