ABSTRACT:
A method and system for repairing a memory. A test and repair wrapper is operable to be integrated with input/output (I/O) circuitry of a memory instance to form a wrapper I/O (WIO) block that is operable to receive test and repair information from a built-in self-test and repair (BISTR) processor. Logic circuitry associated with the WIO block is operable generate a current error signal that is used locally by the BISTR processor for providing a repair enable control signal in order to repair a faulty memory portion using a redundant memory portion without having to access a post-processing environment for repair signature generation.
