The metal oxide semiconductor field effect transistor (MOSFET) works on a similar principle, but the diode is buried within the MOSFET.

A semiconductor device may include at least one metal oxide field-effect transistor (MOSFET).

The invention relates to a power supply structure of a memory, which comprises a charge pump, a readout voltage regulator, a decoupling capacitor and an MOS (Metal Oxide Semiconductor) transistor;
