[PConline News] Micron, one of the leading names in the memory industry, has recently unveiled a new NVDIMM-N memory module. This innovative product combines DDR4 DRAM with NAND flash memory, offering a unique advantage: it can quickly shut down and transfer data from the memory to the flash storage, ensuring that no data is lost during an unexpected power failure.
Interestingly, Micron has been exploring non-volatile DIMM (NVDIMM) technology since the DDR3 era. Unlike traditional RAM, which loses all data when the power is cut off, NVDIMM retains its contents even without power. This makes it ideal for applications where data integrity is critical. Previously, NVDIMM modules came in 8GB and 16GB variants, but this latest release jumps to 32GB, doubling the capacity and offering more performance and reliability.
The new NVDIMM-N model is designed as an N-type module, using NAND flash as a backup for data retention. In contrast, the F-type version is purely flash-based. The latest 32GB DDR4 NVDIMM-N includes a 64GB SLC NAND chip. In case of a power outage, the onboard FPGA will instantly move all active data to the flash memory, ensuring seamless recovery once power is restored.
To maintain power during shutdowns, the module can be connected to an external power source. Two options are available: either use a power line connected to an AGIGA PowerGEM capacitor or draw power from the 12V slot on the DIMM. While Micron is currently in the trial production phase for the 32GB NVDIMM-N, they haven't announced a specific release date yet.
Additionally, it's worth noting that Micron and Intel are continuing to develop their 3D XPoint technology, which could eventually unify memory and storage in future systems. This advancement may lead to even more efficient and reliable data handling in next-generation computing platforms.
