AMD Working on Vertical (3D) Stacking of DRAM onto processors
News from the other side of the globe reaches us and is saying that AMD is working hard to embed DRAM and System Memory onto processors into one single package. The RAM would get connected through silicon-through-channels.
In many segments manufacturers are already working on similar technologies, look at HBM2 and NAND 3D Vertical stacking. For a processor, this, however, is new as the aforementioned technologies are based on a package-on package design. .The new tech would not make the actual memory faster but will make it work more efficient in overall performance.
Intel is doing similar things with under the codename foveros

Though I am not sure about the significance of this one but AMD Radeon Technologies Group (RTG) head Raja Koduri slipped in an interview that they are not fabbing one, but two Polaris based GPUs....
AMD Working on 16-Core Processor with Integrated PCI Express 3.0 Controller - 01/17/2014 03:17 PM
In a document published by AMD some new information surfaced. It seems that AMD is working on a new 16-core processor, and that is a true 16 cores, thus not 8 cores and 4 GPU cores or anything. And no...
AMD working on new Ruby Technology Demo ? - 09/20/2013 11:28 AM
Back in the days AMD released the Ruby Technology demo whenever graphics cards where released. Who doesn't remember that ? Today an AMD press-release entered the good old mail-box showing a screensho...

Eventually we will get to the point where the only way to increase ram speed will be to have it on package with the CPU, you can already see this a little bit with how overclocking focused boards often only have 2 ram slots placed as close as they can get them to the cpu to increase ram overclocking ability.
So I wouldn't mind it at all if we loose the ability for upgrading ram or changing ram speed without replacing the whole CPU package, as long as the ram speeds and efficiencies on those packages are better than what would be possible with the current method of having separate ram modules.
I wonder if at some point we'll actually lose the freedom to pick the amount/speed of DRAM we want, or if this will remain limited to select embedded use-cases.

I would very much mind loosing the freedom to choose what amount and what kind of RAM I will have in my system. There are huge differences in both price and performance between modules and I doubt that either intel or AMD will have so much combinations to satisfy everyone's needs.
So even though I agree that to get better performance something like this must happen, I hope that they would introduce possibility to install RAM modules as a service or DIY slot on the CPU, but I guess that is far into the future, as they first need to make it a reality and show that it is actually significantly better than what we have now.

Couldn't we get a bunch of truly fast RAM inside the CPU package, but then the user could add more in the typical DIMM form? It would be slower, but if the system ran out of what's shipped with the CPU, the system could use it. It would still be faster than an SSD (bandwidth and latency wise). Who knows how much the CPU package would initially ship with anyway.

Yeah "right to repair" n all that.. definitely skirting further n further away and closer to none at all.
No way the CPU OEMs are going to match anything anywhere near the current dedicated modular RAM market - it's just not profitable or realistic
Any smart memory manufacturer is lobbying to protect their piece of the market. Not like they are against performance - loss of profit. Likely a halfway solution between them & the cpu makers will arise.
