Difference Between Volatile and Non-Volatile Memory

No.	Volatile Memory	Non-Volatile Memory
1	Volatile memory is computer memory that requires power to maintain the stored information.	Non-volatile storage is computer memory that can retain stored information even when not powered
2	Volatile memory retains the information as long as power supply is on, but when power supply is off or interrupted the stored memory is lost. Therefore it is used for temporary storage.	Non-volatile memory is typically used for the task of secondary storage, or long-term persistent storage.
3	Its Faster in Speed	Its Slow in Speed
4	Examples are: RAM,DRAM,SDRAM	Examples are:ROM,PROM,EPROM,EEPROM
