Patent abstract
A semiconductor chip device include device state fuses that may be used to configure various device states and corresponding security levels for the semiconductor chip as it transitions from wafer manufacturing to provisioned device. The device states and security levels prevent the semiconductor chip from being accessed and exploited, for example, during manufacturing testing. A secure boot flow process for a semiconductor chip over its lifecycle is also disclosed. The secure boot flow may start at the wafer manufacturing stage and continue on through the insertion of keys and firmware.
