3 NVDIMM-N Overview The Figure below is an overview of the NVDIMM-N showing its main components and system interfaces. Core to the NVDIMM-N are the DDR4 DRAM devices that allow the NVDIMM-N to operate as an RDIMM. The components that allow the NVDIMM-N to persist data are the Controller, Flash, and Power Voltage Regulators that are also integrated on the DIMM. Figure 1. NVDIMM-N Overview Topics: • Normal Operation • Backup to Flash • Restore from Flash Normal Operation NVDIMM-Ns are installed in server memory slots. From a hardware perspective, the NVDIMM-Ns appear to the processor as standard DDR4 RDIMMs. They are initialized during BIOS POST, and the CPU can access DRAM data on the NVDIMM-N using standard DDR4 memory load/store transactions.

NVDIMM-N Overview
The Figure below is an overview of the NVDIMM-N showing its main components and system interfaces. Core to the NVDIMM-N are the
DDR4 DRAM devices that allow the NVDIMM-N to operate as an RDIMM. The components that allow the NVDIMM-N to persist data are
the Controller, Flash, and Power Voltage Regulators that are also integrated on the DIMM.

NVDIMM-Ns are installed in server memory slots. From a hardware perspective, the NVDIMM-Ns appear to the processor as standard
DDR4 RDIMMs. They are initialized during BIOS POST, and the CPU can access DRAM data on the NVDIMM-N using standard DDR4
memory load/store transactions.
