Non-volatile memory maker Everspin says it's getting ready to ship non-volatile 256-megabit DDR3 chips and expects they'll soon be installed in your next server or array.

256 megabits is just 32 megabytes, which doesn't sound worthy of a DIMM slot even if it can sustain writes 100,000 times faster than is possible with NAND flash.

The company thinks there are some applications where users will find that speed irresistible, but CEO Phill LoPresti told us that for now the main market for the product is system builders and integrators.

He thinks server makers will appreciate the possibilities of non-volatile RAM as an alternative, both because it offers better protection and because it's faster. 256 Mb is enough for data-shuttling roles so it will be worth a DIMM slot.

Everspin is sampling the product now, so server-makers can start to play with it at their convenience. LoPresti said he thinks it may find friends among manufacturers of RAID controllers as well.

He thinks Everspin can win such customers without fighting with Intel, as that company has promised it will start to make money from its own non-volatile RAM, 3D Xpoint.

LoPresti added that Intel will do well as a replacement for flash or other disk, but that it's not as well suited to write caching as Everspin's tunnel junction based ST-MRAM.

Everspin didn't name any server makers who've bought into its plans for the new product, but can point to IBM's utilization of its earlier products in POWER 8 systems.
