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.
