DDR4 technology already is available in Netlist (NLST) HyperCloud memory - now available from IBM (as HCDIMM) and HP (as HP Smart Memory HyperCloud or HDIMM). NLST HyperCloud will supplant LRDIMMs - as LRDIMMs are based on NLST IP. LRDIMMs had copied NLST IP - and been aggressive about it. However they have suffered a defeat in their challenge of Netlist IP - as NLST patents '537 and '274 have survived reexamination at the USPTO with all claims intact - which is a powerful signal of what is to come for Netlist vs. Inphi (basically Inphi will be unable to challenge NLST IP in court !). LRDIMMs also underperform - as they have high latency and are unable to reach full speed at full memory loading (3 DPC at 1333MHz is not achievable by LRDIMMs on HP servers). Therefore the market for LRDIMMs will be served by NLST HyperCloud - and if LRDIMMs are sold maybe NLST will get damages from that eventually (or LRDIMMs could face recall ?). LRDIMMs are also at end-of-life because they have implemented NLST IP improperly - by choosing a centralized buffere which leads to asymmetrical line lengths and skew (thus the higher latency issues). Netlist says they will be the first proprietary standard which will be adopted by the industry - for DDR4. And DDR4 is looking more and more like NLST HyperCloud. So expect JEDEC to license NLST IP sometime before finalization of the DDR4 standard. Until DDR4 appears you will only be able to buy NLST HyperCloud to do what you thought LRDIMMs could (as LRDIMMs under a cloud) - however for DDR4 expect licensees to also be making memory along with NLST.

So will DDR4 require TSV? Will Micron manufacture 3x nm without Inotera or Elpida this year? Next year?

Micron is definitely leading the DDR space in the front.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
