Editing Application checkpointing (section)

===Mementos===
Mementos is a software system that transforms general-purpose tasks into interruptible programs for platforms with frequent interruptions such as power outages. It was designed for batteryless embedded devices such as [[RFID tag]]s and smart cards which rely on [[Energy harvesting|harvesting energy]] from ambient background sources. Mementos frequently senses the available energy in the system and decides whether to checkpoint the program due to impending power loss versus continuing computation. If checkpointing, data will be stored in a [[non-volatile memory]]. When the energy becomes sufficient for [[reboot (computing)|reboot]], the data is retrieved from non-volatile memory and the program continues from the stored state. Mementos has been implemented on the [[MSP430]] family of [[microcontrollers]]. Mementos is named after [[Christopher Nolan]]'s [[Memento (film)|''Memento'']].<ref>Benjamin Ransford, Jacob Sorber, and Kevin Fu. 2011.
