These modules are based on 3D Xpoint memory, a form of phase-change non-volatile memory.
The modules are DDR4 socket compatible and operate on the same buses/channels as DDR4 DRAM. The modules can be configured to operate as volatile memory capacity indistinguishable from DRAM from a software perspective, or as non-volatile memory that retains its data like an SSD, but at 225 times faster data access than a typical NAND-based drive.
The modules are available in capacities of 128Gbytes, 256Gbytes, and 512GBytes, and are compatible with the second-generation Intel Xeon processor family. The modules have two operational modes – app direct mode and memory mode — allowing users to tailor their persistent memory solutions to specific workloads.
