Intermittent computing, by its very nature, requires non-volatile memory to store data between outages. However, many typical non-volatile options (such as NAND) are infeasible for a variety of reasons (such as write limitations¹⁾). As a result, most research and development has focused on a few specialized forms of non-volatile memory.

Most common in MSP430 microcontrollers.

Present on the Apollo4. Unlike most forms of RAM, MRAM stores data using magnetized bits, rather than through electrical charge or current. The primary disadvantage of this memory type is vulnerability to write errors, necessitating a higher current than is strictly required to reduce errors from occurring.
