Abstract: A location of at least one fail bit to be repaired in a memory block of a memory is extracted from at least one memory test on the memory block. An available repair resource in the memory for repairing the memory block is obtained. It is determined whether a Constraint Satisfaction Problem (CSP) containing a plurality of constraints is solvable. The constraints correspond to the location of the at least one fail bit in the memory block, and the available repair resource. In response to determining that the CSP is not solvable, the memory block is marked as unrepairable or the memory is rejected. In response to determining that the CSP is solvable and has a solution satisfying the constraints, the at least one fail bit is repaired using the available repair resource in accordance with the solution of the CSP.

Abstract: A method of testing a non-volatile memory (NVM) array includes heating the NVM array to a target temperature. While the NVM array is heated to the target temperature, a current distribution is obtained by measuring a plurality of currents of a subset of NVM cells of the NVM array, each NVM cell of the NVM array is programmed to one of a logically high state or a logically low state, and first and second pass/fail (P/F) tests on each NVM cell of the NVM array are performed. A bit error rate is calculated based on the current distribution and the first and second P/F tests.
