Intel executives revealed the timing of the introduction of "3D XPoint DIMM" memory substitution for explosive speed / large capacity DRAM

DIMM type DRAM substitute memory using Intel's "3D XPoint" technology "3D XPoint DIMMIt is clear that it will appear in 2018. It seems that it will come to realize explosion speed and large capacity memory of DRAM + SSD's good point.

You can find out about the technology of the memory "3D XPoint" developed to fill the gap between memory (DRAM) and SSD by looking at the following article.

Intel Optane SSD DC P4800X, a nonvolatile high-speed memory that is faster than NAND (SSD) and cheaper than memory (DRAM) is finally coming - GIGAZINE


The 3D XPoint memory between the memory and the SSD corresponds to two types, nonvolatile storage purpose and DIMM type substitute memory use for DRAM. As the 3D XPoint memory for storage use, the enterprise-oriented SSD "DC P4800X" of the PCI-Express interface was launched in October 2017 and the SSD adopted by consumer 3D XPoint "Intel Optane SSD 900PThe series is released in November 2017.


Optane SSD 900P also has 2.5 inch form factor SSD of U.2 interface.


For the DIMM-type DRAM replacement memory "3D XPoint DIMM" that was delayed in presentation compared to 3D XPoint memory for storage, Senior Vice President Navin Shenov of Intel's data center group representative at UBS Global Technology Conference said " 3D XPoint DIMM will be on sale ". Intel predicts that 3D XPoint DIMM will reach $ 800 million (about 90 billion yen) by 2021.


It is unlikely that 3D XPoint DIMMs are fully compatible with DDR4 memory, which is now standard DRAM memory, and server side support is required. Also, the establishment of the NVDIMM-P standard for installing the nonvolatile memory in the DIMM slot is scheduled for 2018, and it is obvious whether the 3D XPoint DIMM conforms to NVDIMM-P or uses its own interface It has not become. Considering such circumstances, the release of 3D XPoint DIMMIntel Xeon Scalable ProcessorAnandTech points out that it may be fitted with the refreshing time of.
