===Non-volatile SRAM===
[[Non-volatile SRAM]] (nvSRAM) has standard SRAM functionality, but they save the data when the power supply is lost, ensuring preservation of critical information. nvSRAMs are used in a wide range of situations{{snd}}networking, aerospace, and medical, among many others<ref>{{cite book|title=Computer organization.|url=https://archive.org/details/isbn_9780071143097|url-access=registration|publisher=McGraw-Hill|location=[S.l.]|isbn=978-0-07-114323-3|edition=4th|date=1996-07-01}}</ref>{{snd}}where the preservation of data is critical and where batteries are impractical.
