Abstract:
An integrated circuit, comprising:a connection pad for receiving an external signal for stipulating one of at least three different organization forms for operating the integrated circuit; and a control circuit for setting one of the three different organization forms, said control circuit having a first resistor series circuit, a second resistor series circuit connected in parallel to said first resistor series circuit, an input and an output, said input and one of said first and second resistor series circuits being connected to said connection pad, and said control circuit being able to generate an output signal having any of at least three different states at said output to identify a respective organization form, depending on the external signal applied to said connection pad, said output signal being produced by tapping off and comparing a first potential on said first resistor series circuit and a second potential on said second resistor series circuit.
