Persistent Memory

Overview

Persistent memory is a new 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. We will continue leading the way on persistent memory development, spearheading R&D efforts on promising new technologies like 3D XPoint™ memory and other storage-class solutions that will provide unprecedented system performance, capacity and reliability.

Supported Products


NVDIMMs

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.

3D XPoint Technology

3D XPoint™ technology is a breakthrough memory technology that addresses the need for nonvolatile, high-performance, high-endurance, high-capacity storage-class memory. With up to 1,000 times lower latency and exponentially greater endurance than NAND, 3D XPoint technology can deliver game-changing performance for big data applications when paired with DRAM. Its ability to enable high-speed, high-capacity data storage close to the processor will create new possibilities for system architects and promises to enable entirely new applications. The significant ecosystem enablement necessary to employ 3D XPoint technology on the server memory bus is currently underway with key partners. 3D XPoint technology presents a compelling vision for what the future of persistent memory – and high-performance computing – will look like.
