Abstract
A computer platform is disclosed. The computer platform comprises a non-volatile memory to store fuse override data; and a system on chip (SOC), coupled to the non-volatile memory, including a fuse memory to store fuse data and security micro-controller to receive the fuse override data and perform a fuse override to overwrite the fuse data stored in the fuse memory with the fuse override data.
Claims23
A computing device comprising:
- a non-volatile memory to store fuse override data;
- and
- a system on chip (SOC), coupled to the non-volatile memory, including:
- a fuse memory to store fuse data;
- and
- security micro-controller to receive the fuse override data and perform a fuse override to overwrite the fuse data stored in the fuse memory with the fuse override data, including debug fuse override hardware to indicate when fuse override is enabled.
A method comprising:
- verifying that a fuse override is enabled at a system on chip (SOC);
- retrieving fuse override data from a non-volatile memory;
- and
- performing a fuse override at the SOC, including overwriting fuse data stored in a fuse memory with the fuse override data.
A system on chip (SOC) comprising:
- a fuse memory to store fuse data;
- and
- security micro-controller to receive fuse override data from a non-volatile memory and perform a fuse override to overwrite the fuse data stored in the fuse memory with the fuse override data, including debug fuse override hardware to indicate when fuse override is enabled.
At least one computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:
- verify that a fuse override is enabled at a system on chip (SOC);
- retrieve fuse override data from a non-volatile memory;
- and
- perform a fuse override at the SOC, including overwriting fuse data stored in a fuse memory with the fuse override data.
