Micron’s Super-Fast New 32GB NVDIMM

 

Switch TrackMicron Technology has introduced a 32GB NVDIMM-N.  Perhaps the most important thing about this device is not so much its high density as the fact that it runs at higher bus speeds than competing NVDIMMs, doing 2933 megatransfers per second (MT/s), a speed that Micron representatives tell us is required to support Intel’s Skylake processor.

Up to this point NVDIMM-Ns have been limited to 2400 MT/s, which is fast enough for Broadwell, but which misses the mark for Skylake.  Design is tricky even at this slower speed, requiring a number of expensive high-speed multiplexers in the DRAM’s critical speed path.

“Multiplexers?”  Yes, NVDIMMs use them, even though no other kind of DIMM does.  The Memory Guy can explain why, having just finished a report covering the NVDIMM market and technology.

Here’s a little refresher for those who either don’t remember or never knew that NVDIMM-N requires multiplexers.  The NVDIMM-N looks to the system like a standard Continue reading
