CMOS
Complementary Metal
Oxide Semiconductor
A type of semiconductor. CMOS semiconductors use
both NMOS (negative polarity) and PMOS (positive
polarity) circuits. Since only one of the circuit types is on
at any given time, CMOS chips require less power than
chips using just one type of transistor. This makes them
attractive for use in battery-powered devices
