A memory component includes multiple fuses, a memory array having a multiple blocks, and control logic operatively coupled with the memory array and the plurality of fuses. The control logic is to perform operations including detecting a failure to completely erase a block of the plurality of blocks in response to an attempted erasure of the block; receiving a blow fuse command in response to the failure to completely erase the block; and blowing a fuse, of the plurality of fuses, coupled with the block, to make the block electrically inaccessible to the control logic in response to receipt of the blow fuse command.
