What is the full form of CMOS?
The full form of CMOS is Complementary Metal-Oxide-Semiconductor. CMOS is an integrated circuit built on a printed circuit board. It is a battery-powered memory chip that effortlessly holds the initialisation data. The BIOS uses this data to turn on the device, i.e., during the bootup process.
- The complementary word refers to the user charge, that is, either PMOS (positive MOS) or NMOS (negative MOS). CMOS utilises one charge at a time.
- CMOS consumes less power since charges can remain for a prolonged period of time in one phase and, therefore, only consume energy whenever necessary.
- Transistors focused on CMOS do not heat up and yield a high speed.
Applications of CMOS
- Static RAM
