Patent ID: 7958286

Claim:
Programmable information selection system for an integrated circuit, comprising: a database integrated within an integrated circuit, the database having a plurality of different sets of identification information that pertain to the integrated circuit stored within it; programmable circuitry within the integrated circuit coupled to the database and coupled to receive at least one external analog voltage control signal as an input, the programmable circuitry being configured to select from the plurality of different sets of stored identification information depending at least in part upon the at least one external analog voltage control signal and to store the selected set of stored identification information for later reporting to an external device as identification information that identifies the integrated circuit to the external device; and external resistor circuitry coupled to the programmable circuitry to provide the at least one external analog voltage control signal, the external resistor circuitry being configured to provide a given voltage for the at least one external analog voltage control signal.
