Abstract
Systems and methods for detecting states are disclosed. An information handling system may include a processor and a plurality of information handling resources communicatively coupled to the processor via the common control line. The processor may be configured to produce a first signal on a common control line. Each of the plurality of information handling resources may include a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag.
Claims6
An information handling system, comprising:
- a processor configured to produce a first signal on a common control line;
- and
- a plurality of information handling resources communicatively coupled to the processor via the common control line, each of the plurality of information handling resources including a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag;
- each tag including:
- a diode having threshold voltage and configured to provide a current path in response to the first signal exceeding the signal threshold associated with the particular information handling resource;
- and a current source communicatively coupled to the diode and configured to increase a magnitude of a current of the common control line by driving a current through the current path.
