DDR4 will eventually license NLST HyperCloud IP. LRDIMMs are already at end-of-life - as they have adopted a bad implementation of the NLST IP. DDR4 is more closely copying it. LRDIMMs are currently only made by Inphi (others have backed off - IDTI and Texas Instruments). However Inphi has been aggressive in copying NLST IP - but recently their reexamination of NLST patents '537 and '274 were re-validated by USPTO with ALL claims intact. This is going to bode badly for NLST vs. Inphi. LRDIMMs will either be recalled, or negotiate a license from NLST. DDR4 should license NLST IP before finalization as well. Currently NLST HyperCloud is selling through IBM (as HCDIMM) and HP (as HP Smart Memory HyperCloud). It is the only memory capable of 1333MHz at 3 DPC on HP servers. Inphi-based LRDIMMs have latency issues (because of their use of asymmetrical lines) - and they are unable to deliver 1333MHz at DPC (but 1066MHz). How about covering NLST IP for a change - as it will be adopted by DDR4.
