Full Form of CMOS » Complementary Metal Oxide Semiconductor

CMOS Stands for Complimentary Metal Oxide Semiconductor. It is a physical part of the motherboard. basically, It is a special type of memory chip, that is installed on the computer motherboard, which stores the Basic Input/Output System (BIOS) settings.

It also provides time and date settings and instructs the computer to perform many basic functions such as the Boot Device Priority function. It is powered by a CMOS battery. In 1963, Frank Wanlass discovered CMOS. When he was doing some experiments in Fairchild Semiconductor. He also patent on it

What is main fuction of Cmos chip?

The CMOS chip stores the BIOS’s default setting, time and date, Boot Device Priority function, as well as, Cmos maintain the different settings such as-

  • Date – Sets the system date.
  • Time – Sets the system time.
  • SATA1 – Configures the devices connected to the primary SATA channels.
  • SATA2 – Configures the connected device to have other SATA channels.
  • E-SATA1 – Configures external primary SATA channels to the connected device.
  • System Information – Provides all the information about the hardware it also shows the total memory in the system.

What is CMOS Battary in computer?

CMOS is usually powered by the use of a CR2032 cell battery. This coin-sized lithium-ion battery is called a CMOS battery.

The BIOS setup of the computer is stored on the CMOS chip rather than in RAM or other memory. It has a storage capacity of 256 bytes. This setup can be maintained by the computer every time it is restarted or turned on.

Even when the computer is turned off, this CMOS battery continues to supply 3 volts of electricity to the CMOS memory chip. The life of a CMOS battery is about 5-10 years.
