Abstract:
An apparatus includes a memory sub-system comprising a plurality of memory blocks and a memory block defect detection component. The memory block defect detection component is to set, for a memory block among the plurality of memory blocks, a first block defect detection rate and determine whether the first block defect detection rate is greater than a threshold block defect detection rate for the at least one memory block. In response to a determination that the first block defect detection rate is greater than the threshold block defect detection rate for the memory block, the memory block defect detection component is to assert a program command on the memory block determine whether a program operation associated with assertion of the program command on the at least one memory block is successful. In response to a determination the program operation is unsuccessful, the memory block defect detection component is to determine that a failure involving a plane associated with the memory block and another plane of the memory sub-system has occurred.
