Volatile memory is computer storage that only maintains its data while the device is powered. Most RAM (random access memory) used for primary storage in personal computers is volatile memory. ... Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost.

What is volatile memory?

Volatile memory is computer memory that requires power to maintain the stored information. Most modern semiconductor volatile memory is either Static RAM (see SRAM) or dynamic RAM (see DRAM). ... Dynamic RAM is more complicated to interface to and control and needs regular refresh cycles to prevent its contents being lost.

What types of memory is volatile?

RAM is volatile memory used to hold instructions and data of currently running programs. It loses integrity after loss of power. RAM memory modules are installed into slots on the computer motherboard. ROM (Read-Only Memory) is nonvolatile: data stored in ROM maintains integrity after loss of power.
