Define the difference between static RAM and dynamic RAM?

The RAM family comprises two important memory devices that are static RAM (SRAM) and dynamic RAM (DRAM). The main difference between them is the lifetime of the data they store SRAM retains its contents as long as electrical power is applied to the chip if the power is turned off or lost temporarily, its contents will be lost forever. DRAM, on the other hand, has an extremely short data lifetime-typically about four milliseconds and this is true even when power is applied constantly.
