SMART’s DDR4 NVDIMMs combine nonvolatile 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. NVDIMMs support Autonomous Self Refresh (ASR). SMART’s patented ASR feature allows the NVDIMM to independently initiate a backup in the event of an OS crash (operating system), CPU fault, MCU fault (Memory Controller Unit), BIOS hang, blue screen, or other motherboard failures which result in a hang without power loss where the customer has data in the DIMM that they want to save and recover after a system is reset to recover from the hang.
