In this video, we'll wire up an EEPROM (28C16) so we can read its contents. We'll also take a look at the data sheet to learn how to program it, and try programming some values. Finally, we'll see how the EEPROM can be used to replace any combinational logic circuit such as the 7-segment decoder from the previous video (
