Intel releases Optane DIMMs
 

3D XPoint memory onto the DDR4

Chipzilla has released its Optane DIMMs and introduced 3D XPoint memory onto the DDR4 memory bus although don't expect to see them any time soon.

First unveiled in 2015 and due to launch a year later - a target the company would miss - Intel's Optane represents the company's first attempt at creating a hybrid dynamic and non-volatile memory type. As with other hybrid memory formats, the idea is that the performance of non-volatile flash memory will increase to the point that volatile dynamic memory, which loses its contents unless constantly refreshed, will no longer be necessary.

The modules that have been known under the Apache Pass codename will be branded as Optane DC Persistent Memory, to contrast with Optane DC SSD.

The Optane DC Persistent Memory modules will be initially available in three capacities: 128GB, 256GB and 512GB per module. This implies that they are probably still based on the same 128Gb 3D XPoint memory dies used in all other Optane products. The modules are pin-compatible with standard DDR4 DIMMs and will be supported by the next generation of Intel's Xeon server platforms.
