DEVICE AND SYSTEM INCLUDING ADAPTIVE REPAIR CIRCUIT

摘要

A device or subsystem includes an internal circuit configured to perform at least one function, an input-output terminal set and a repair circuit. The input-output terminal set includes multiple normal input-output terminals connected to an external device via multiple normal signal paths and at least one repair input-output terminal selectively connected to the external device via at least one repair signal path. The repair circuit repairs a failed signal path included in the normal signal paths based on a mode signal and fail information signal, where the mode signal represents whether to use the repair signal path and the fail information signal represents fail information on the normal signal paths. Using the repair circuit, various systems adopting different repair schemes may be efficiently repaired and cost of designing and manufacturing the various systems may be reduced by supporting different repair schemes by using the same configuration of the device.
