Abstract: The present invention relates to a method and circuit for selectively repairing an embedded memory module having memory elements in an integrated circuit chip. The method includes performing a plurality of tests on the embedded memory module under operating conditions to identify a plurality of non-operational memory elements in the embedded memory module and, in response to identifying the non-operational memory elements, generating a plurality of corresponding repair solutions. The method further includes storing the plurality of corresponding repair solutions in a non-volatile storage element and determining from a mask a subset of the plurality of repair solutions that should be restored.

Abstract: A design structure for implementing redundancy programming in a memory macro of an integrated circuit chip. It is assumed that all fails are row fails until determined to be bitline fails, circuits for implementing a method wherein it is assumed that all fails are row fails until determined to be bitline fails and test patterns are passed back to the failure detecting circuit when a wordline destination of the test patterns has previously been determined to be failing, and the test patterns and resultant patterns are passed between the memory macro and a test engine via logic paths connecting the memory macro to other circuits in said integrated circuit chip.

Abstract: A system that includes a controller for enabling an enumeration operation. The enumeration operation is performed by a controller (110) and logic elements (120) in a system, such that each logic element in the system assigns itself a unique identifier. Each logic element can then be controlled by another source or have a means to communicate with other logic elements in the system. The unique identifier enables greater system flexibility, thereby reducing cost and improving efficiency.

Abstract: A method and apparatus for correcting embedded memory that has been identified as being defective by a memory controller. The address of the defective memory is provided by the memory controller to Built-In Test (BIST) logic in combination with a Built-In Redundancy Analyzer (BIRA) to replace the defective memory element with a redundant element.
