Abstract
An integrated circuit (IC) device package that includes permanent identification regarding the device characteristics, wherein the permanent identification are at or below the surface of the package and may indicate the operating frequency of an IC die within the package, as well as voltage requirements, etc.
Claims20
An integrated circuit device comprising:
- a plurality of pins;
- a package encapsulating at least one integrated circuit die and coupled to the plurality of pins;
- at least one conductive indicator coupled through a portion of the package to individual pins of the plurality of pins to indicate a characteristic of said at least one integrated circuit by encoding the characteristic into the package based on a conductive state of each said at least one conductive indicator.
An integrated circuit device comprising:
- a package containing an integrated circuit die and having a ground plane disposed therein and a plurality of conductive traces, wherein a portion of each conductive trace is coupled to the ground plane;
- and
- a plurality of detection points coupled to the package, wherein individual conductive traces are coupled to individual detection points, wherein the plurality of traces indicate an individual characteristic of the integrated circuit by encoding the individual characteristic into the package based on a conductive state of each of the plurality of conductive traces.
A method of determining a characteristic of an integrated circuit device having a package, said method comprising the steps of:
- encoding the characteristic permanently into the package by cutting metal traces disposed within package material;
- querying the device for the characteristic including the step of reading the encoded characteristic from the metal traces within the package material.
