Please help with practice problem.

a. There are "two conditions" that allow current to flow through a MOSFET, and "two conditions" that would not allow current to flow. Write down what these conditions are:

b. Consider a n-channel MOSFET and a p-channel MOSFET. How would you connect these two transistors in order to make a basic CMOS Inverter, as discussed in class.

c. Now consider a floating gate, containing electrons. Use Gauss' Law to explain whether or not inversion can occur in the channel if a positive gate voltage were to be applied

d. Depending on whether or not current flows through the channel, what does this tell you about whether or not you have stored a "0" or a "1"?

e. Use principles of Coulomb's Law to explain how you would remove electrons from the floating gate (i.e. to "flash" your flash memory device)
