NVDIMM: Persistent Memory
Netlist NVDIMM DDR4 JEDEC Standard Module Combines DRAM
Capacity/Performance with NAND Persistence
Non-volatile dual in-line memory module (NVDIMM) is persistent memory that combines DRAM
and storage in a 288pin DIMM socket. The NVDIMM operates as a standard registered DIMM
(RDIMM) and drops into the DDR4 memory channel. The device has a DDR4 protocol that is
JEDEC compliant and has DRAM latency and bandwidth. A non-volatile persistent memory
solution that provides performance and persistence for a broad range of enterprise server and
storage applications.
Applications:
• Logging
• Journaling
NVDIMM Operation

NVME SSD*
• 1000x lower latency vs.
NVMe SSD
The Netlist NVvault NVDIMM-N implements the JEDEC compliant DDR4 RDIMM and NVDIMM-N
and logic subsystem that preserves the contents of the DRAM during system power losses.
The NVDIMM consists of NAND components to store the DRAM data, isolation components to
decouple the DIMM from the system during power failure, a backup power circuit to provide
power to the DIMM during power failure, and a logic device to control the operations. Nvvault
backups to and restores from NAND allowing data to be preserved through a power loss.
During this operation, the DRAM is completely isolated from the normal system memory bus
and cannot be accessed by the system. The system controls the configuration and operation of
NVvault via a register set accessible through the SMBus.
