"We are excited to be the first IP provider to offer a GDDR6 PHY solution with industry-leading performance designed with power efficiency and high signal margins for these applications."

Micron Technology, Inc., a leading memory and storage provider, today announced with Rambus Inc., Northwest Logic and Avery Design, their efforts to deliver a comprehensive solution for GDDR6, the world's fastest discrete memory. This first-of-its-kind solution would enable GDDR6 use in advanced applications such as high-performance networking, autonomous vehicles, artificial intelligence and 5G infrastructure. Prior generations of GDDR memories, enabled by GPU vendors, were focused exclusively on the graphics market. While this allowed graphics and game console designs to take advantage of the significant performance advantage offered by GDDR, other applications could not because the necessary building blocks were not available.

Rambus, a company that has veered around the line of being an innovative company and a patent troll, has shed some more light on what can be expected from HBM3 memory (when it's finally available). In an investor meeting, representatives from the company shared details regarding HBM3's improvements over HBM2. Details are still scarce, but at least we know Rambus' expectations for the technology: double the memory bandwidth per stack when compared to HBM2 (4000 MB/s), and a more complex design, which leaves behind the 2.5D design due to increased height of the HBM3 memory stacks. An interesting thing to note is that Rambus is counting on HBM3 to be produced on 7 nm technologies. Considering the overall semiconductor manufacturing calendar for the 7 nm process, this should place HBM3 production in 2019, at the earliest.

HBM3 is also expected to bring much lower power consumption compared to HBM2, besides increasing memory density and bandwidth. However, the "complex design architectures" in the Rambus slides should give readers pause. HBM2 production has had some apparent troubles in reaching demand levels, with suspected lower yields than expected being the most likely culprit. Knowing the trouble AMD has had in successful packaging of HBM2 memory with the silicon interposer and its own GPUs, an even more complex implementation of HBM memory in HBM3 could likely signal some more troubles in that area - maybe not just for AMD, but for any other takers of the technology. Here's hoping AMD's woes were due only to one-off snags on their packaging partners' side, and doesn't spell trouble for HBM's implementation itself.

DDR5, the natural successor to today's DDR4 memory that brings with double the bandwidth and density versus current generation DDR4. along with delivering improved channel efficiency, is expected to be available in the market starting 2019. JEDEC, the standards body responsible for the DDR specifications, says that base DDR5 frequencies should be at around DDR5-4800 - more than double that of base DDR4's 2133, but a stone throw away from today's fastest (and uber, kidney-like-expensive) 4600 MHz memory kits from the likes of G.Skill and Corsair.

DDR5 is expected to support data rates up to 6.4 Gb/s delivering 51.2 GB/s max, up from 3.2 Gb/s and 25.6 GB/s for today's DDR4. The new version will push the 64-bit link down to 1.1V and burst lengths to 16 bits from 1.2V and 8 bits. In addition, DDR5 lets voltage regulators ride on the memory card rather than the motherboard. CPU vendors are also expected to expand the number of DDR channels on their processors from 12 to 16, which could drive main memory sizes to 128 GB from 64 GB today. Whether this will be good for end-users in relation to DDR5 memory prices remains open for debate; however, considering the rampant memory prices this side of 2017, chances are it won't be unless supply increases considerably.

Rambus Inc. today announced the availability of its High Bandwidth Memory (HBM) Gen2 PHY developed for GLOBALFOUNDRIES high-performance FX-14 ASIC Platform.
