Found another typo on the MOSFET page of the Semiconductor book here:
The red text should read "may approach hundreds of millions." The adjective/numerical value hundreds is plural, and not exact, so the rest should be plural as well.The insulated-gate field-effect transistor (IGFET), also known as the metal oxide field effect transistor (MOSFET), is a derivative of the field effect transistor (FET). Today, most transistors are of the MOSFET type as components of digital integrated circuits. Though discrete BJT's are more numerous than discrete MOSFET's. The MOSFET transistor count within an integrated circuit may approach hundreds of a million.
