What is Persistent Memory?

Persistent Memory is non-volatile, byte addressable, low latency memory with densities greater than or equal to Dynamic Random Access Memory (DRAM). It is beneficial because it can dramatically increase system performance and enable a fundamental change in computing architecture. Applications, middleware, and operating systems are no longer bound by file system overhead in order to run persistent transactions.

Persistent Memory is used today in database, storage, virtualization, big data, cloud computing/IoT, and artificial intelligence applications. Persistent Memory is supported by an industry-wide hardware, software, standards, and platform ecosystem. The SNIA Persistent Memory Technology Focus Area includes information on technical work group activities developing a NVM Programming Model, and education and outreach activities including an educational library of Persistent Memory webcasts, videos, tutorials, and white papers.
