In August 2018 IBM announced that it adopted Everspin's 256Mb STT-MRAM chips in its enterprise SSD FlashSystem. Now IBM announced that it's latest FlashCore modules will use Everspins 1Gb STT-MRAM chips.

Using MRAM instead of DRAM memory enabled IBM to remove the relatively large supercapacitors (used to make the DRAM non-volatile) and so the company was able to reduced the size of its drives and switch to a standard 2.5-inch U.2 drive form factor.

In June 2019 Everspin announced that it completed the development activity and entered the pilot production phase of its 28 nm 1-Gigabit STT-MRAM chips.
