Definition: NMOS

(Negative-channel MOS) Pronounced "n-moss." A type of transistor used for logic and dynamic memory chips (DRAM). NMOS transistors are faster than their PMOS counterpart, and more of them can be put on a single chip. In CMOS logic, an NMOS transistor is paired with a PMOS transistor. See CMOS, PMOS, MOSFET and NMOS vs. PMOS.
