   320C31 KGD Definitions
Known Good Die - Die that have the same quality and reliability as the equivalent packaged part.
Probed die - 25°C DC probed die that have not undergone any special testing. Also called bare die.
Commercial level KGD - KGD that has been processed to meet the same parameters as the equivalent commercial temperature device (usually 0°C to 70°C)
Military level KGD - KGD that has been processed to meet the same parameters as the equivalent military temperature device (-55°C to 125°C)
