Apple attaches their laptop RAM the same way all smartphones do. It’s a wide bus with LPDDR, which makes it an unusual configuration amongst laptops, but it’s technically conventional.
AMD’s Strix Halo chips are the same.
When we talk ‘packaging’, we’re talking putting chips on advanced substrates with denser wires than one could possibly get on a motherboard (or a ‘mini’ motherboard which is kinda what Apple/smartphone RAM is packaged on), stuff silicon fabs have to do:

That’s (as I understand it) a misconception.

And HBM falls into this bucket. The way its hooked up to the CPU is physically different than PC RAM sticks, or Apple’s RAM.
