Persistent Memory and NVDIMM Special Interest Group

The SNIA Persistent Memory and NVDIMM SIG contributed to Revision 1 of JESD248, DDR4 NVDIMM-N Design Standard (revision 1.0) which was released September 2016.  This standard defines the electrical and mechanical requirements for 288-pin, 1.2 Volt (VDD), Double Data Rate, Synchronous SDRAM Nonvolatile Dual In-Line Memory Modules with NAND Flash backup (DDR4 NVDIMM-N). Read more about the standard here.  The SIG was recently awarded Best of Show at Flash Memory Summit 2017 for their work on the standard with JEDEC.

The Persistent Memory and NVDIMM Special Interest Group (PM/NVDIMM SIG) revised their charter in 2018 to accelerate awareness and adoption of Persistent Memory (PM) and Non-Volatile Dual In-line Memory Modules (NVDIMMs) for competing architectures.  The PM/NVDIMM SIG will:

  • Educate on the types, benefits, value, and integration of Persistent Memories
  • Communicating usage of the NVM Programming Model developed to simplify system integration of current and future PM technologies
  • Influence and collaborate with middleware and application vendors to support Persistent Memories
  • Developing user-perspective case studies, best practices, and vertical industry requirements
  • Coordinate with industry standard groups and promote industry standards related to PM and NVDIMM
  • Synchronize and communcate a common Persistent Memory taxonomy

The Persistent Memory NVDIMM SIG is a member communiity under the SNIA and the Solid State Storage Initiative (www.snia.org/forums/sssi), which will provide logistical and promotional support for the SIG.

The Persistent Memory NVDIMM SIG includes vendors AgigA Tech, Calypso Systems, Intel, Micron, Netlist, Samsung, SK Hynix, SMART Modular Technologies, Spin Transfer, Toshiba,  Viking Technology, and Western Digital.

On this page, you will find up-to-date news, event listings, webcasts, FAQs, white papers, and articles about Persistent Memory.  Scroll down the page and see a wealth of educational content on this important topic.

JEDEC and SNIA awarded Best of Show at Flash Memory Summit 2017

JEDEC Announces Support for NVDIMM Hybrid Memory Modules
JEDEC's JC-45 Committee has approved the first standards for support of “hybrid” DDR4 memory modules which are defined as modules that plug into standard dual in-line memory module (DIMM) sockets and appear like a DDR4
SDRAM to the system controller, yet contain non-volatile (NV) memories such as NAND Flash on the module. The press release linked above features a quote from the Co-Chairs of the PM/NVDIMM SIG.

NVDIMM SIG honored by peers at SNIA 2015 Symposium, winning the award for most significant contributions by a SNIA committee in 2014.

NVDIMM - Applications are Here! 
Get a glimpse of the future of Persistent Memory - it's NOW! Join SNIA NVDIMM Special Interest Group in another in our series of webcasts on the NVDIMM Cookbook - how to incorporate NVDIMM into your systems and what non-volatile DIMM applications now available. We'll even highlight some of the "knobs" to turn to optimize use of NVDIMM in your applications to ease the way to simple, plug-n-play adoption!

NVDIMM Cookbook SNIA Tutorial
Non-Volatile DIMMs, or NVDIMMs, have emerged as a go-to technology for boosting performance for next generation storage platforms. The standardization efforts around NVDIMMs have paved the way to simple, plug-n-play adoption. If you're a storage developer who hasn't yet realized the benefits of NVDIMMs in your products, then this tutorial is for you! We will walk you through a soup-to-nuts description of integrating NVDIMMs into your system, from hardware to BIOS to application software. We'll highlight some of the "knobs" to turn to optimize use in your application as well as some of the "gotchas" encountered along the way.

Persistent Memory Advances:  Solutions with Endurance, Performance, and Non-Volatility
Persistent memory solutions deliver the endurance and performance of DRAM coupled with the non-volatility of Flash. This webinar will update you on the latest solutions for enterprise server and storage designs, and provide insights into future persistent memory advances. A specific focus will be NVDIMM solutions, with examples from the member companies of the SNIA NVDIMM Special Interest Group.

NVDIMM - Persistence Pays
Non-Volatile DIMMs, or NVDIMMs, provide a persistent memory solution with the endurance and performance of DRAM coupled with the non-volatility of Flash. This webinar provides a general overview of this emerging technology and why the industry is starting to take notice. You will learn what an NVDIMM is, how it works, where it fits and why every system architect should consider them for their next generation enterprise server and storage designs.  View on demand HERE.

Storage in the DIMM Socket SNIA Tutorial
This tutorial focuses on how IT managers have begun seeking out new ways for flash to be deployed in the data center in order to take greater advantage of the performance and latency benefits. With traditional interfaces such as SAS, SATA and PCIe already taking advantage of flash and deployed, the focus has shifted to non-traditional interfaces in order to further penetrate current infrastructure. This has led to the emergence of new solutions that leverage the DDR3 interface, utilizing existing DIMM slots in server hardware

Providing Storage at Memory Speed Using NVDIMMs - SNIA NVDIMM SIG Hosted Panel Presentation at Open Server Summit 2016

NVDIMMs are persistent memory modules that reside on the DDR DRAM channel, combining volatile DRAM and nonvolatile flash memory. Under normal power conditions, an NVDIMM operates just like DRAM with ultra low latency and essentially infinite endurance, but is still nonvolatile. During a power failure or system crash, the data in the DRAM is transferred to the flash and can be restored when normal conditions resume.  Persistent memory enables applications to run faster due to greater I/O performance. Typical areas of interest include databases, Web 2.0, analytics, OLTP, and video and image processing.
