Abstract: One embodiment of the present invention includes a hard-coded first device ID. The embodiment also includes a set of fuses that represents a second device ID. The hard-coded device ID and the set of fuses each designate a separate device ID for the device, and each device ID corresponds to a specific operating configuration of the device. The embodiment also includes selection logic to select between the hardcoded device ID and the set of fuses to set the device ID for the device. One advantage of the disclosed embodiments is providing flexibility for engineers who develop the devices while also reducing the likelihood that a third party can counterfeit the device.
