Making this sort of innovation happen was a broadly collaborative effort. AMD did much of the initial the heavy lifting, designing the interconnects, interposer, and the new DRAM type. Hynix partnered with AMD to produce the DRAM, and UMC manufactured the first interposers. JEDEC, the standards body charged with blessing new memory types, gave HBM the industry's blessing, which means this memory type should be widely supported by various interested firms. HBM made its way onto Nvidia's GPU roadmap some time ago, although it's essentially a generation behind AMD's first implementation.
AMD did create the technology itself. Not simply the interposer. It all started 7 years ago, within AMD, without Hynix in the picture. This information came from Joe Macri himself, the man who oversaw the creation of HBM. AMD sought Hynix in order to produce the first chips, as AMD has no fabs with which to produce DRAM.
AMD then applied for a JEDEC open standard license. This license ensures that AMD has equal-rights access to the production of HBM, as does nVIDIA, and that prices will be negotiated as per the consent of the members of the JEDEC group.
Knucklehead... I am using logic as well as knowledge of how the industry functions. I would have thought that our last exchange, in terms of Open Standards, would have led you to make an effort and correct your ignorance on the topic at hand. Open Standards are about adding a degree of fairness into everyday business dealings. The dog eat dog variant of Capitalism, you espouse in your posts, need not apply here. We're also not talking about State-Capitalist Patent enforcement of proprietary technologies. We're discussing the JEDEC Open Standards and licensing as well as the rules which accompany the acquisition of such a license from the JEDEC group.
This is not the first time either. AMD developed GDDR3 and GDDR5 as well:
“We do internal development with partners, we then take that development to open standards bodies and we open it up to the world,” he said. “This is how Nvidia got GDDR3 and how they got GDDR5. This is what AMD does. We truly believe building islands is not as good as building continents.” - Joe Macri
Macri is probably in a position to know: Besides being AMD’s Chief Technology Officer, Macri has long been a chairman at JEDEC, the group that blesses memory standards for the industry. AMD did indeed beat Nvidia in introducing graphics cards with GDDR3 and GDDR5, but that always brings concerns over yields with new technology.

HBM’s performance-to-power ratio is so good and appealing, Macri said he expects the new memory to be adopted in other areas besides big GPUs. We can expect HBM to appear on CPUs with integrated graphics chips, as well as servers and workstations. That would appear to put HBM on a collision course with a similar memory technology Intel and Micron are working on called Hybrid Memory Cube, or HMC. HMC is an advanced stacked memory design, but unlike AMD, Intel and Micron are trying to adopt it without the slow rule-by-committee of JEDEC.
