Difference Between CMOS and MOS

CMOS vs MOS

Summary: Difference Between CMOS and MOS is that RAM chips, flash memory chips, and other types of memory chips use complementary metal-oxide semiconductor (CMOS pronounced SEE-moss) technology because it provides high speeds and consumes little power. While MOS stands for Metal Oxide Semiconductor which is used to build transistors.

CMOS

Some RAM chips, flash memory chips, and other types of memory chips use complementary metal-oxide semiconductor (CMOS pronounced SEE-moss) technology because it provides high speeds and consumes little power. CMOS technology uses battery power to retain information even when the power to the computer is off. Battery-backed CMOS memory chips, for example, can keep the calendar, date, and time current even when the computer is off. The flash memory chips that store a computer’s startup information often use CMOS technology.

MOS

MOS stands for Metal Oxide Semiconductor which is used to build transistors. You can create up to many transistors by using MOS. MOS consists of three layers including semiconductor silicon layer, metal conductor and insulating silicon layer. For example MOSFET is a type of transistor that is usually used amplifying electronic signals.
