[Product Brief] SMART Modular DDR4 NVDIMM

Future of Persistent Memory DRAM and SSD Form Factors Aligned with New System Architectures




SMART Modular’s DDR4 NVDIMMs combine non-volatile memory functionality with high speed DDR4 DRAM technology. DDR4 NVDIMMs provide a persistent memory solution to significantly accelerate application performance in server and storage appliances.

Features & Benefits

  • Fits standard 288-pin DIMM socket
  • During normal operation, NVDIMM will function as a standard RDIMM module
  • During a power loss, the contents of the DRAM are automatically backed up to Flash
  • NVDIMM with Encryption also offered as an option

Secure Storage Technologies

SafeStor™ Technology

  • SMART's DDR4 NVDIMMs feature proprietary SafeStor™ technology, the engine which initiates backup and restore operations from the host controller
  • The NVDIMMs also support multiple command delivery options to trigger SafeStor™ backup during a host detected power outage and recovery event
  • The SafeStor™ engine also employs multi-channel, fast NAND and high speed switching circuitry to provide robust backup and restore capability, all while functioning as a JEDEC standard DDR4 or DDR3 RDIMM during normal operation


NVDIMM with Encryption

  • For financial industry and other applications where protecting data on the NVDIMM is critical
  • IEEE developed AES-XTS 256 standard is used to encrypt data
  • Key must be supplied by host during POST through the 12C interface to support backup with encryption
  • AES-XTS encryption may be enabled or disabled through an NVDIMM 12C registe
