Nonvolatile DIMM (NVDIMM) technology fills the memory performance gap between DRAM and NAND—combining the speed of DRAM with the persistent storage of NAND for increased system performance and reliability.


Bridging the Gap Between DRAM Speed and NAND Nonvolatility

NVDIMMs are an RDIMM form factor that merges NAND Flash, DRAM, and an ultracapacitor power source into a memory subsystem—delivering DRAM read/write performance and backing up its data if power is interrupted.

NVDIMMs provide performance, cost, and data security advantages for a wide range of enterprise-class server and storage applications. They are ideal for environments that need persistent DRAM capability to optimize frequent access to big data’s complex information sets.

They’re also eco-friendly—while batteries start to lose their ability to hold a charge after several hundred charge/discharge cycles, the ultracaps used in NVDIMMs have hundreds of thousands of cycles, greatly extending their life. And unlike many batteries, ultracaps are lead-free and not prone to leaking.

NVDIMM Alliance

We’ve partnered with other industry experts—like AgigA Tech, Intel, Samsung, SK hynix, and Microsoft—to form SNIA’s NVDIMM Special Interest Group (SIG). Our goal is to help communicate the benefits of NVDIMMs more broadly, to educate customers on how to design in NVDIMMs efficiently, and to make it easy for customers to find the products that integrate with NVDIMMs.
