CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

The COSMAC (Complementary Symmetry Monolithic Array Computer) is an 8-bit microprocessor family introduced by RCA. It is historically notable as the first CMOS microprocessor. [1] The first production model was the two-chip CDP1801R and CDP1801U, which were later combined into the single-chip CDP1802. [2]
The microprocessor recognised the DEC PDP-8 minicomputer instruction set. As such it was sometimes referred to as the CMOS-PDP8. Since it was also produced by Harris Corporation, it was also known as the Harris HM-6100. By virtue of its CMOS technology and associated benefits, the 6100 was being incorporated into some military designs until the ...
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Intel 4004, the first single-chip microprocessor CPU, launched in 1971. ... included chips such as Alice that were manufactured using a 1.5 μm CMOS process.
Another change was the move to CMOS gates as the primary method of building complex CPUs. CMOS had been available since the early 1970s; RCA introduced the COSMAC processor using CMOS in 1975. [43] Whereas earlier systems used a single transistor as the basis for each "gate", CMOS used a two-sided design, essentially making it twice as ...
A 1 MHz chip used in KIM-1 and other single board computers in the mid-1970s. 6502A A 1.5 MHz chip used in Asteroids Deluxe and at 2 MHz in the BBC Micro: 6502B Version of the 6502 capable of running at a maximum speed of 3 MHz instead of 2 MHz. The B was used in both the Apple III and early Atari 8-bit computers, each running at ~1.8 MHz. [c ...
The Western Design Center (WDC) 65C02 microprocessor is an enhanced CMOS version of the popular nMOS-based 8-bit MOS Technology 6502.It uses less power than the original 6502, fixes several problems, and adds new instructions.
