  • Patent number: 11127712
    Abstract: Systems and methods of providing redundant functionality in a semiconductor die and package are provided. A three-dimensional electrical mesh network conductively couples smaller semiconductor dies, each including circuitry to provide a first functionality, to a larger base die that includes circuitry to provide a redundant first functionality to the semiconductor die circuitry. The semiconductor die circuitry and the base die circuitry selectively conductively couple to a common conductive structure such that either the semiconductor die circuitry or the base die circuitry is able to provide the first functionality at the conductive structure. Driver circuitry may autonomously or manually, reversibly or irreversibly, cause the semiconductor die circuitry and the base die circuitry couple to the conductive structure. The redundant first functionality circuitry improves the operational flexibility and reliability of the semiconductor die and package.
