Persistent Memory


Persistent memory is an addition to the memory/storage hierarchy that bridges the gap between DRAM and storage, allowing greater flexibility in data management by providing nonvolatile, low-latency memory closer to the processor. Because it resides on the DRAM bus, persistent memory can provide ultra-fast DRAM-like access to critical data. Combining the data reliability of traditional storage with ultra-low latency and high bandwidth enables designers to optimize their systems and manage data in a whole new way.

Persistent memory is ideal for environments that require frequent access to large, complex data sets and environments that are sensitive to downtime caused by power failures or system crashes. Applications include big data analytics, storage appliances, RAID cache, in-memory databases, metadata servers that store indexes and on-line transaction processing.

Micron’s 8GB DDR4 NVDIMM represents the first product in our persistent memory family. Our DDR4 NVDIMMs combine DRAM, NAND flash and a power source in a memory subsystem to deliver high performance plus the reliability of backing up data if power is interrupted.

Supported Products


NVDIMMs combine the speed of DRAM, the persistent storage of NAND and an optional power source in an RDIMM form factor, creating a memory subsystem that delivers increased system performance and reliability. NVDIMMs are ideal for applications that are sensitive to down time and require high performance to enable frequent access to large data sets, such as big data analytics, storage appliances, RAID cache, in-memory databases and on-line transaction processing. NVDIMMs are available from Micron today.
