Noun
nMOS
(electronics) A MOSFET with an n-type channel (a semiconductor doped with an element creating a surplus of electron carriers).
Additionally, obtaining low-threshold devices on both PMOS and NMOS devices would likely require the use of different metals for each device type, introducing additional complexity to the fabrication process. Source: Internet
An advantage of CMOS over NMOS logic is that both low-to-high and high-to-low output transitions are fast since the (PMOS) pull-up transistors have low resistance when switched on, unlike the load resistors in NMOS logic. Source: Internet
As an example, here is a NOR gate implemented in schematic NMOS. Source: Internet
At the time the processor was designed, the number of transistors that could be economically put on a chip was very constrained (around a few thousand), so it made sense to rely on RAM instead of allocating expensive NMOS chip area for CPU registers. Source: Internet
Furthermore, because polysilicon has the same bandgap as the underlying silicon channel, it is quite straightforward to tune the work function to achieve low threshold voltages for both NMOS and PMOS devices. Source: Internet
The channel can contain electrons (called an nMOSFET or nMOS), or holes (called a pMOSFET or pMOS), opposite in type to the substrate, so nMOS is made with a p-type substrate, and pMOS with an n-type substrate (see article on semiconductor devices ). Source: Internet
