Abstract
Systems and methods are disclosed for generating dynamic super blocks from one or more grown bad blocks of a non-volatile memory ('NVM'). In some embodiments, a dynamic super block can be formed by striping together a subset of memory locations of grown bad blocks from one or more dies of a NVM. The subset of memory locations may be selected based on at least one reliability measurement of the subset of memory locations. In some embodiments, in response to detecting one or more access failures in a portion of the dynamic super block, the NVM interface can retire at least a portion of the dynamic super block. In some embodiments, the NVM interface can reconstruct a new dynamic super block from the dynamic super block by progressively increasing the size of the new dynamic super block.
