发明名称 METHOD AND SYSTEM FOR ITERATIVELY TESTING AND REPAIRING AN ARRAY OF MEMORY CELLS
摘要 A memory system includes an array of memory cells and a repair module. Multiple memory cells in the array are redundant to other memory cells in the array. The repair module iteratively tests the array. During the iterative testing of the array, the repair module, during each test of the array, (i) identifies one or more defective memory cells in the array, if any, and (ii) in response to one or more defective memory cells being identified during the test, respectively replaces the one or more defective memory cells with one or more memory cells that are redundant to other memory cells in the array. The repair module performs the iterative testing of the array until (i) the repair module does not detect a defective memory cell or (ii) no memory cells of the memory cells that are redundant remain available for replacement of a defective memory cell.
