A brief about CMOS

Because of the initial cost of the Complementary Metal Oxide Semi-Conductor (CMOS) technology, memory, transistors and large parts of most microprocessors were once reserved for storing the startup configuration of the PC. With technology advances and lower costs, however, CMOS technology is now even being used throughout the PC. CMOS memory requires only about one-millionth of an amp to hold any data stored on it. Using only a lithium battery, CMOS memory is able to store the startup configuration of a PC for many years. The term CMOS is still synonymous with PC’s startup configuration data
