Systems and methods for providing component characteristics

摘要

Systems and methods are disclosed for providing a signal indicative of one or more types of individual measurable device characteristic/s that are unique to a given electronic device by providing a signal indicative of the measurable and unique device characteristic/s in a passive manner from the electronic device. The signal indicative of one or more types of individual measurable device characteristic/s may be so provided without requiring operational power to be applied to any active electronic circuitry of the device, and without requiring any power to be generated by the device.

主权项

1. An information handling system, comprising:
at least one electronic device comprising:
at least one first electronic component comprising active circuitry coupled to a first circuit path of the electronic device and having a measurable device characteristic that is unique to the electronic component, the device characteristic being an electronic characteristic of circuitry of the first electronic component that is measurable by circuitry external to the electronic device using the first circuit path of the electronic device, andat least one passive circuit component that is separate and different from the first electronic component, the passive circuit component coupled to a second circuit path of the electronic device that is separate from and unconnected to the first circuit path, the passive circuit component having a passive electrical characteristic that is discernible by circuitry external to the electronic device using a second circuit path of the electronic device,where the passive electrical characteristic is selected to be indicative of the measurable device characteristic of the first electronic component; and measurement circuitry external to the at least one electronic device and coupled to the second circuit path of the electronic device and configured to discern the passive electrical characteristic without providing any power to any active circuitry components of the electronic device.
