Everspin Technologies announced that it started to ship pre-production customer samples of its 28 nm 1Gb STT-MRAM chips in December 2018. Everspin already announced that it started to sample these new 1Gb STT-MRAM chips in November 2018.
In November 2017 Everspin announced it will delay its 1Gb STT-MRAM chips as its focus has shifted to its 256 Mb STT-MRAM chips. It is great, tough, to see Everspin progressing with its larger MRAM chip and we hope that mass production will begin, as planned, in the middle of 2019.
Everspinâs 1 Gb product family includes both 8-bit and 16-bit DDR4 compatible (ST-DDR4) interface versions of the device and are available in a similar BGA package to Everspinâs existing portfolio of 256 Mb parts.
