In March 2017 Everspin announced its nvNITRO line of storage accelerators, with 1GB and 2GB capacities, based on the company's 256Mb DDR3 ST-MRAM chips. Everspin is accepting orders for these accelerators which should start shipping by the end of the year.
In the video above you can see a recent demonstration by Everspin of how these nvNITRO accelerators provide superior latency determinism enabling a Low Latency Write Buffer for applications such as Apache Log4J.
