Key Features
NVDIMMs combine the high-speed access of DRAM with the persistence of NAND flash storage. They are designed to fit into standard DIMM slots on memory buses. Different standards exist, such as NVDIMM-N (DRAM is memory mapped, Flash is for backup), NVDIMM-F (Flash is memory mapped, slower latency), and NVDIMM-P (Persistent, aims for both byte-addressable and block access). They are crucial for enterprise environments where data loss due to power failure must be prevented while maintaining high per
