Abstract: Various systems and methods for secure microcode updates are described herein. An integrated circuit for secure microcode updates, including a hash circuit to determine a hash of a current patch content, a memory controller to obtain, from an on-die non-volatile memory device, a copy of a previously-determined hash of a previous patch content, and a patch loader to validate the current patch content by comparing the hash of the current patch content with the hash of the previous patch content and apply the current patch content when the current patch content is validated.
