Integrated circuit boot code and fuse storage implemented on interposer-mounted non-volatile memory

摘要

A method and apparatus for replacing a boot ROM and programmable fuses using a non-volatile memory and an interposer is disclosed. In one embodiment, an apparatus includes an integrated circuit (IC) implementing one or more processor cores. The apparatus further includes a non-volatile memory configured to store configuration settings and boot code for the IC. The apparatus further includes an interposer. Both of the IC and the non-volatile memory are mounted on a substrate of the interposer. The IC and the non-volatile memory are electrically coupled to one another through the substrate. During a system boot, the IC may access boot code and configuration settings from the non-volatile memory via electrical connections in the substrate that are externally inaccessible.
