Stacked chip module with integrated circuit chips having integratable and reconfigurable built-in self-maintenance blocks
Abstract:
Disclosed is a stacked chip module incorporating a stack of integrated circuit (IC) chips having integratable and automatically reconfigurable built-in self-maintenance blocks (i.e., built-in self-test (BIST) circuits or built-in self-repair (BISR) circuits). Integration of the built-in self-maintenance blocks between the IC chips in the stack allows for servicing (e.g., self-testing or self-repairing) of functional blocks at the module-level. Automatic reconfiguration of the built-in self-maintenance blocks further allows for functional blocks on any of the IC chips in the stack to be serviced at the module-level even when one or more controllers associated with a given built-in self-maintenance block on a given IC chip has been determined to be defective (e.g., during previous wafer-level servicing). Also disclosed is a method of manufacturing and servicing such a stacked chip module.
