Buffalo Memory launched a new industrial SATA III SSD (the S6C series) that uses Everspin's STT-MRAM as cache memory. As far as we know, this is the first product on the market to use STT-MRAM chips. Buffalo says that by using STT-MRAM cache, they were able to improve performance (access time) and power consumption, and also feature better tolerance to sudden power off.
Buffalo's SSD use Everspin's EMD3D064M 64Mb DDR3 ST-MRAM chips. These feature full DDR3 speed coupled with non-volatility. The EMD3D064M chip is functionally compatible with the industry standard JEDEC specification for the DDR3 interface, providing designers the ability to quickly adopt ST-MRAM in storage and embedded systems.
