NVIDIA Ratchet Level

• The NVIDIA ratchet fuses are burned at the NVIDIA production line.

• These fuses cannot be programmed from software.

• For NVIDIA owned firmware, if any security loophole is found, then based on the criticality of the issue, the NVIDIA ratchet level can be updated.

• An N bit NVIDIA ratchet fuse field can represent numeric value 0-2^N-1. (i.e., an absolute value is programmed in NVIDIA ratchet fuse).
