Looks like this rumor was true. Micron and Intel announced today that KL will be using HMC for on package memory.

W.r.t. HMC, I still don't really get it's benefits. From my understanding is basically moves the memory controller into the DRAM stack. Aren't you increasing latency by doing that? What benefit does that provide (outside of the host processor not needing a terribly intelligent memory controller) Does it simply benefit by fabricating the array management logic in an actual logic process? Or am I just completely misinformed on what HMC is? Any good references or whitepapers on this?
