Abstract
A technique is provided for accumulating failures. A failure of a first row is detected in a group of array macros, the first row having first row address values. A mask has mask bits corresponding to each of the first row address values. The mask bits are initially in active status. A failure of a second row, having second row address values, is detected. When none of the first row address values matches the second row address values, and when mask bits are all in the active status, the array macros are determined to be bad. When at least one of the first row address values matches the second row address values, mask bits that correspond to at least one of the first row address values that match are kept in active status, and mask bits that correspond to non-matching first address values are set to inactive status.
