A non-volatile dual in-line memory module is a type of random-access memory for computers. A non-volatile dual in-line memory module (NVDIMM) is a type of random-access memory for computers. An NVDIMM (non-volatile dual in-line memory module) is hybrid computer memory that retains data during a service outage. The NVDIMM exists to leverage the speed of the DRAM bus and of memory accesses. Designed for applications that are sensitive to down time and require high performance to enable frequent access to large data sets, NVDIMMs combine the. In case the name is unfamiliar, NVDIMM stands for “Nonvolatile Dual-Inline Memory Module.
