DDR3
The older high-speed memory technology is still thriving and moving from 30 nm to 20 nm to save power, give it a new lease of life, and cover the gap before DDR4 ships in high volume. DDR3 is currently the mainstream PC technology with voltages of 1.2 to 1.5 V and data transfers up to 2133 Mtransfers/s.

HMC/ HBM is the technology
barunkd   4/11/2014 4:24:41 AM
3D Memory, with its two flavors HMC and HBM, will become the high speed memory of future. They will replace DDR technolog in server application. Besides providing much higher bandwidth than DDR4 (4x to 6x), HMC makes the job of PCB designer easier becuase it is based of serial interface technology where as DDR4 is based on parallel interface technology. But the question is when. There are two challenges. First one is cost, HMC is at least 3x costlier (if not more) than DDR4. And it is not pin replacable, creating the need of fresh board design. Server has long product lifetime, hence this is a challenge to HMC adoption

These aren't even technologies to watch - they are interface solutions to consider.  No, I won't put DDR4 in my smartphone.  No, I won't put embedded DRAM in my server, etc.  Since this article was about 'memory interconnect technologies to watch', why is a serial connected RAM interface like HMC not even mentioned?

I literally lost count of the technical errors in this piece. I suggest readers not rely on it for mission-critical needs.
