Executive Summary
This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price of
Everspin’s EMD3D256M STTMRAM.
Amongst multiple emerging NVM technologies, spin transfer torque magneto resistive RAM (STT-MRAM) has shown significant potential
and market growth driven by low latency storage applications. In 2018 MRAM Market recorded a Revenue of $44 million dollars.
Compound annual growth rate of MRAM market is estimated at 85% between 2018 and 2024.
Magnetoelectronic memories have been employed in numerous information devices because of their nonvolatile characteristics, high
speed and low power consumption. Their high endurance characteristic has made the STT MRAM Memory a good competitor in the
memory industry and promises to pick up significant market shares in the next few years.
Everspin’s STT MRAM component has a compact structure integrating numerous layers that include ferromagnetic material and
antiferromagnetic material forming a magnetic tunnel junction. Different resistive states created in the MRAM memory cell allow read
and write functions. A dielectric layer is coupled between two magnetic materials. A complex fabrication method is used to deposit and
pattern the thin layers that form the STT MRAM memory cell.
Everspin Technologies leads the (STT-) MRAM market. The 256Mb STT MRAM memory uses a 40 nm technology node. The memory is
manufactured along with the CMOS Transistors.
System Plus Consulting presents a deep analysis of Everspin’s EMD3256M STT MRAM Memory. The report includes an analysis of the
package and the dies, the MRAM memory cell and focusing on the layered material that make up the MRAM Cell memory. It also
features a cost analysis and a price estimation of the component; this cost analysis integrates the manufacture of the CMOS transistors
and the MRAM Memory cells. The manufacturing process steps are detailed including the supply chain. The results of manufacturing
cost are used to determine the cost per Mb for Everspin’s STT MRAM Memory.
