Method and structure for external control of ESD protection in electronic circuits

1. A structure for external control of an electrostatic (ESD) discharge protection of one or more electronic devices, comprising:

one or more shunt circuits coupled to the one or more electronic devices;

one or more external contacts coupled to the one or more shunt circuits, wherein any external contact of the one or more external contacts is operable to be coupled to any one of a ground signal, an AC signal and a DC signal to provide external control of the functionality of the one or more shunt circuits through the one or more external contacts; and

one or more power supplies coupled to the one or more shunt circuits wherein one or more supply signals of the one or more power supplies are coupled to the one or more shunt circuits spatially prior to the one or more shunt circuits being coupled to the one or more electronic devices.

2. The structure of claim 1 , wherein the one or more shunt circuits are coupled to a ground at a first terminal and coupled to a supply voltage at a second terminal.

3. The structure of claim 1 , wherein each electronic device of the one or* more electronic devices is coupled to a power supply of the one or more power supplies.

4. The structure of claim 1 , wherein each electronic device of the one or more electronic device has an independent power supply of the one or more power supplies.

5. The structure of claim 1 , wherein the one or more electronic devices comprise one or more cores, said one or more cores coupled to the one or more shunt circuits.

6. The structure of claim 5 , wherein each core of the one or more cores is coupled to a power supply of the one or more power supplies and further coupled to one or more input/output pads.

7. The structure of claim 5 , wherein each core has an independent power supply of the one or more power supplies.

8. A method for external control of one or more ESD devices coupled to one or more protected circuits, comprising one or more of:

for any external contact of one or more external contacts coupled to one or more ESD devices operable to provide ESD protection to the one or more protected circuits performing at least one of the following to provide external control of the functionality of the one or more ESD devices through the one or more external contacts:

grounding the external contact;

one or more of one or more external contacts coupled to the one or more ESD devices;

supplying one or more DC signals to the external contact; and

supplying one or more AC signals to the external contact.

9. The method of claim 8 , wherein the one or more external contacts are coupled to the one or more ESD devices in a one to one correspondence.
