GlobalFoundries' 22FDX with MRAM is Ready

GlobalFoundries on Thursday said that it had completed development of its 22FDX (22 nm FD-SOI) technology with embedded magnetoresistive non-volatile memory (eMRAM). The technology can be used for a variety of applications, including automotive, industrial-grade MCU, and Internet-of-Things (IOT). Several clients of GlobalFoundries are ready to tape out their first 22FDX chips with eMRAM this year.

eMRAM provides a number of advantages when compared to eFlash (which is widely used today) for chips that need relatively high-capacity onboard storage, including higher performance and endurance, but want it all in a single silicon die. MRAM does not involve electric charges or current flows, instead, it uses magnetic storage elements and relies on reading the magnetic anisotropy (orientation) of two ferromagnetic films separated by a thin barrier. The method does not require an erase cycle before writing data, which means additional performance. Furthermore, MRAM can be produced using modern process technologies and has a very high endurance. The technology has some downsides, which will be eventually addressed by fabrication processes that use ReRAM, but GlobalFoundries and Samsung Foundry see a huge potential in MRAM for the vast majority of applications.

    GlobalFoundries is focusing on profitability, not the bleeding edge.

    Woah! What an idea! Make technology decisions based on economic considerations rather than romantic attachments to a favorite way of doing things.

      To be clear I'm not criticizing them for it, although it might be possible to do both (TSMC).

        I'm not criticizing them for it either. Bleeding edge can be fun, and cool. Maybe even profitable. But if doing something else is more profitable, then do that.
