===Non-volatile SRAM===

[[nvSRAM|Non-volatile SRAMs]] have 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—networking, aerospace, and medical, among many others—whereothers<ref>{{cite book|title=Computer organization.|publisher=McGraw-Hill|___location=[S.l.]|isbn=0-07-114323-8|edition=4th ed.}}</ref> —where the preservation of data is critical and where batteries are impractical.
