Persistent memory and NVDIMM terminology
The terminology used in persistent memory tends to overlap and multiple terms may apply for a single component. The HPE 8GB NVDIMM might be referenced using any of the following terms:
- Persistent memory — Memory delivering the performance of memory with the persistence of storage
- SCM — Storage class memory; encompasses emerging technologies
- NVM — Non-volatile memory; includes slower technologies, such as flash memory
- DIMM — Dual Inline Memory Module
- RDIMM — Registered DIMM
- NVDIMM — Non-volatile DIMM; provides persistent memory
- NVDIMM-N — NVDIMM with byte-addressable programming interface to DRAM, backed up to flash memory when needed (energy backed)
- NVRDIMM — NVDIMM that is also an RDIMM
- NVRDIMM-N — NVRDIMM that is also an NVDIMM-N
The HPE 8GB NVDIMM Single Rank x4 DDR4-2133 Module is not any of the following:
- UDIMM — Unbuffered DIMM
- LRDIMM — Load reduced DIMM
