Abstract
A circuit and method of testing a memory and calculating a repair solution for a given address location includes pausing a built in self test (BIST) operation on detection of a failing memory output data of an integrated circuit. During the pause, the circuit and method analyzes 'n' number of groups of the failing memory output data during 'n' cycles using analysis logic and calculating a repair solution. Normal operations can be resumed.
