PMOS logic
open-in-new
<p>PMOS or pMOS logic (from p-channel <a href="/facts/Metal%E2%80%93oxide%E2%80%93semiconductor/eTDJT2Km">metal–oxide–semiconductor</a>) is a family of <a href="/facts/Digital_Circuit/3kJcKbkw">digital circuits</a> based on <a href="/facts/MOSFET/eTDJT2Km">p-channel</a>, <a href="/facts/Enhancement_mode/KB0o8lya">enhancement mode</a> <a href="/facts/MOSFET/eTDJT2Km">metal–oxide–semiconductor field-effect transistors</a> (MOSFETs). In the late 1960s and early 1970s, PMOS logic was the dominant semiconductor technology for <a href="/facts/Integrated_circuit/fjn6vg7C">large-scale integrated circuits</a> before being superseded by <a href="/facts/NMOS_logic/6hup3T21">NMOS</a> and <a href="/facts/CMOS/NJIWYgBl">CMOS</a> devices. </p>
