MRAM-Info just published a great interview with Dr. Saied Teharni, Everspin's COO. Everspin is the world's leading MRAM company (spun off from Freescale), and are producing MRAM chips since 2006. Dr. Saied reveals plans for higher-density MRAM in 2009 - 16Mbit. Today's chips only go to 4Mbit. He also predicts that by 2015 MRAM will be able to compete with DRAM and FLASH (NOR) with densities.
MRAM is one of the most exciting Spintronics technologies, being commercialized today.
