RAM is volatile memory used to hold instructions and data of currently running programs. It loses integrity after loss of power.
Static random access memory (SRAM) loses its content when powered down, and is classified as volatile memory. The memory is volatile because there is no data when power is restored to the device. Another example of volatile memory is the dynamic random access memory (DRAM) used in all desktop computers and laptops.
