  • Memory block allocation by block health
    Patent number: 9959067
    Abstract: An individual block health metric value calculated for each of a plurality of blocks from a combination of factors including at least program-erase cycle count and error rate is used to order the plurality of blocks in order of block health metric values in an ordered list. Subsequently, a block may be selected for use according to a position of the block in the ordered list.

  • Tag-based wear leveling for a data storage device
    Patent number: 9740425
    Abstract: A data storage device includes a memory. A method includes de-allocating a first region of a group of regions of the memory during a wear leveling process based on a determination that the first region is associated with a first tag of a set of tags. Each region of the group of regions is assigned to a tag of the set of tags based on a health metric associated with the region. The health metric is based on a bit error rate (BER), a program/erase cycle (PEC) count, a PEC condition metric, or a combination thereof. In response to selecting the first region, information is copied from the first region to a second region of the memory during the wear leveling process.
