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).
