• ROM- ROM is an example of non-volatile memory. ROM is called non volatile because it is permanent memory. ROM that is read only memory is non volatile because all the data in it doesn't get erased after shutting down the computer and restarting it. 
• Flash memory-Flash memory is a type of erasable read-only memory (EEPROM) that clears and rewrites data in chunks for fast, energy-efficient access and rewriting. Flash memory, or flash storage, is non-volatile, which means it remains viable even without an active power source.
• EVMs (Electronic Voting Machines)-Electronic Voting Machines (EVM) introduced in India in 1982 allow the citizens to vote electronically and ease the job of the Election Commission of India in counting the votes. Electronic Voting Machines (EVM) is an example of non-volatile memory.
