Abstract:
1. An integrated circuit chip having multiple functional options, comprising: a function programming circuit comprising a control unit controlling said integrated circuit chip operated in a first mode or in a second mode; a connection transmitting a first signal when said integrated circuit chip is operated in said first mode, and transmitting a second signal to select one of said multiple functional options when said integrated circuit chip is operated in said second mode, wherein said control unit comprises first and second MOS circuits and an inverter, wherein a channel of said first MOS circuit has said first signal pass therethrough and is connected to said connection, wherein a channel of said second MOS circuit has said second signal pass therethrough and is connected to said connection to select one of said multiple functional options, and wherein a terminal of said inverter is connected to a gate terminal of said first MOS circuit, and another terminal of said inverter is connected to a gate terminal of said second MOS circuit; a semiconductor substrate; a redistribution metal over said semiconductor substrate; and a solder bump connected to an I/O pad of said redistribution metal.
