This is exactly what Apple has done, but it does mean soldered memory, as socketed memory at these speeds still hasn't happened. In the server market that is pretty unpopular (even the hyperscalars are apparently reusing DDR4 with CXL in newer machines). DDR6 apparently has twice the memory bandwidth of DDR5 so that will bring it back in line, to around 1TB/s for 12 channels, so comparable but still with standard memory sticks.

If you don't have to worry about replaceable sticks and users choosing their own memory manufacturer, speed and size then you can shorten the traces and improve connectivity including the bus width and its latency. I can't help but think the DIMM format is coming to an end.

The thing is, it doesn't have to do anything. It is busy getting bailed out, I guess.
