ARM announced that it is developing a compiler for embedded MRAM (eMRAM) for use with Samsung Foundry's 28nm fully-depleted silicon-on-insulator (FDSOI) integrated circuit manufacturing process. ARM completed its first eMARM IP test chip tape out, and the compiler will be available for use by lead partners in 4Q18.

ARM says that the eMRAM compiler can generate instances to replace Flash, EEPROM and slow SRAM/data buffer memories with a single non-volatile fast memory – particularly suited for cost- and power-sensitive IoT applications. The eMRAM can be integrated with as few as three additional masks, while embedded flash requires greater than 12 additional masks at 40nm and below.

In 2014 Crocus Technology announced that ARM licensed the company's Magnetic Logic Unit (MLU) technology, a CMOS based rugged magnetic technology.
