Abstract

One embodiment provides a memory module that enables online repair of defective memory cells. The memory module includes a memory array storing data, a self-test controller coupled to the memory array and configured to perform a self-test on a region within the memory array without interrupting operations of the memory module, and a memory-repair module configured to repair a defective memory cell identified by the self-test controller.
