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.

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.
