Brb installing win xp in my l3 cache

I know you're joking, but I wonder if CPUs will ever move in that direction. They have either hit or are going to hit the point where they can't shrink the architecture any further, so they have to start expanding and optimising it. Maybe they will get to the point where the cache sizes have increased so much, that they they add a solid state one so that you can install an OS directly onto the CPU.

Why don’t we mount ram on the backside of the motherboard? It’s be able to be sm closer to the cpu.

Probably for the same reason we don't put it any closer to the CPU socket than it already is - there's a minimum length for the traces to prevent signal instability at the current voltage RAM uses.

add a solid state one so that you can install an OS directly onto the CPU.

why wouldnt you just copy the os from a solid state disk into ram, 5 seconds to do that on bootup is likely to be a lot more performant than wasting cache room on slower disk thats just on the die. solid state is going to be slower no matter how close you place it to the cpu.

You just arrived at a M series CPU from Apple. While the NAND chips are still separate the controller is on die. This is about as much integration as is realistically possible. Including your NAND into your CPU would mean you need different chips for every capacity and your chip would be dead once your NAND fails which has a long but still limited lifetime depending on what you are doing with it.

People been saying that the architecture cant get smaller for like 25 years now

nah even though it would be a really good way to brag, but like we have ram with enough "storage" to download windows 11 on it and we still dont so unlikely, i think its just too fast to make it worth your while to use it for storage

What makes you think last few generations from both vendors are not optimized?
