Micron's 32GB NVDIMM Delivers 2933 MT/s Speeds to Eliminate Storage Bottlenecks

At the SC17 show, Micron Technology, Inc. announced a new 32GB NVDIMM-N offering twice the capacity of existing NVDIMMs, providing system designers and original equipment manufacturers with new flexibility to work with larger data sets in fast persistent memory.

Persistent memory delivers a balance of latency, bandwidth, capacity and cost by delivering ultra-fast DRAM speeds for critical data. What sets it apart from standard server DRAM is its ability to preserve information in the event of a power loss.

NVDIMM has emerged as a critical persistent memory technology due to its ability to deliver the performance levels of DRAM combined with the persistent reliability of NAND. It reduces the bandwidth gap between memory and storage.

VMware and Dell are collaborating with Micron to increase the performance for virtualized applications.


  • Nonvolatile registered DIMM (NVRDIMM)
  • DDR4 RDIMM, NF (NAND Flash) and PowerGEM management integrated in single module
  • Persistent energy source options
    • Option 1: Battery-free power source (Power-GEM)
    • Option 2: Persistent DDR4 12V pin
      • 32GB (4 Gig x 72) DDR4 RDIMM
      • 64GB SLC Flash
      • DDR4 functionality and operations supported as defined in the component data sheet
      • JEDEC compliant DDR4 288-pin dual in-line memory module connector
      • Fast data transfer rates: PC4-2933, PC4-2666, or PC4-2400
      • VDD = 1.20V (typical)
      • VPP = 2.5V (typical)
      • VDDSPD = 2.2-2.8V
      • Supports ECC error detection and correction
      • Nominal and dynamic on-die termination (ODT) for data, strobe, and mask signals
      • Low-power auto self refresh (LPASR)
      • On-die VREFDQ generation and calibration
      • Dual-rank, comprised of TwinDie, x4 DRAM components
      • On-board I2C temperature sensor with integrated serial presence-detect (SPD) EEPROM
      • 16 internal banks; 4 groups of 4 banks each
      • Fixed burst chop (BC) of 4 and burst length (BL)of 8 via the mode register set (MRS)
      • Selectable BC4 or BL8 on-the-fly (OTF)
      • Gold edge contacts
      • Halogen-free
      • Fly-by topology
      • Terminated control, command, and address bus
  • Battery-free power source (ultra capacitor based PowerGEM)
  • Powers the Micron NVDIMM when the host system loses power
  • 5-year operating life
  • 0C to 55C operating range (standard)
  • No catastrophic failure modes
  • RoHS-, REACH-, and UL-compliant
  • Nonvolatile memory (NVM) system-level features
    • In-system health monitoring of PowerGEM and NF
    • Automatic history tracking: tracks critical internal system parameters
    • Interlocked control sequence for safe and reliable operation (system protocol)
    • I2C command/control bus
    • Multiple backup trigger methods

ADR, SAVE_n (DDR4 Pin 230) assert, pull up to 2.5V through resistor on motherboard
RESET_n (DDR4 Pin 58)
SMBus commanded

  • Module height: 31.25mm (1.23in)
  • Operating temperature
  • Commercial (0C ≤ TOPER ≤ +95C) None
  • Package: 288-pin DIMM (halogen-free) Z
  • Frequency/CAS latency: 0.68ns @ CL = 21 (DDR4-2933) -2G9
