[PConline News] Micron, one of the leading names in the memory industry, has recently unveiled a new NVDIMM-N memory module. This innovative solution merges DDR4 DRAM with NAND flash technology, offering a key advantage: it can be powered down quickly while preserving data. When power is cut, the system automatically transfers all active data from the DRAM to the NAND flash, ensuring no loss of information during unexpected shutdowns.
Interestingly, Micron has been exploring non-volatile DIMM (NVDIMM) technology since the DDR3 era. NVDIMMs are designed to retain data even when power is removed, unlike traditional RAM that loses all its contents upon shutdown. These modules have previously come in 8GB and 16GB DDR4 versions, but this latest release doubles the capacity to an impressive 32GB, marking a significant step forward in performance and reliability.
The new NVDIMM-N model is specifically designed for data backup using NAND flash. In contrast, the NVDIMM-F variant functions purely as a flash-based module. The latest 32GB DDR4 NVDIMM-N includes a 64GB SLC NAND chip. In the event of a power failure, the onboard FPGA will instantly move all active data to the flash storage, ensuring system continuity and data integrity.
During a power outage, the module can maintain operation by connecting to an external power source. There are two options available: either use a dedicated AGIGA PowerGEM capacitor connected via the power line, or draw power from the DIMM’s 12V slot using a battery. Although Micron is currently in the trial production phase for the 32GB NVDIMM-N, they haven’t announced a specific release date yet.
In related news, Micron and Intel are continuing their development of 3D XPoint technology, which promises to bridge the gap between memory and storage. As this technology matures, we may soon see a future where memory and flash are unified, revolutionizing how data is accessed and stored in computing systems.
