Four Foundries Back MRAM
Four major foundries plan to offer MRAM as an embedded memory solution by this year or next, setting the stage for what finally could prove to be a game-changer for this next-generation memory technology.
GlobalFoundries, Samsung, TSMC and UMC plan to start offering spin-transfer torque magnetoresistive RAM (ST-MRAM or STT-MRAM) as an alternative or a replacement to NOR flash, possibly starting later this year. This represents a big shift in the market, because until now only Everspin has shipped MRAM for various applications, such as a battery-backed SRAM replacement, write-cache and others.
