Abstract
It is checked, using machine learning, whether at least one fail bit in a memory block of a memory is unrepairable, according to a location of the at least one fail bit, and an available repair resource in the memory. When the checking indicates that the at least one fail bit is not unrepairable, it is determined whether a CSP containing 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 the checking, using the machine learning, indicating that the at least one fail bit is unrepairable, the memory block is marked as unrepairable or the memory is rejected, without making further determinations as to repairability of the memory block.
