Class Information
Number: 257/296
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Field effect device > Having insulated electrode (e.g., mosfet, mos diode) > Insulated gate capacitor or insulated gate transistor combined with capacitor (e.g., dynamic memory cell)
Description: Subject matter wherein the device gate acts as a capacitor (i.e., wherein a positive potential placed on the gate electrode creates a negative charge on the other side of the insulator in the semiconductor material of the device, and vice versa) or the device is a transistor and it is combined with a capacitor.
