Abstract (en)

[origin: WO2020251708A1] Memory management and erasure decoding for a memory device are described. A memory device may identify charge leakage associated with one or more memory cells, and may determine whether to invert a logic state stored by one or more memory cells to improve the likelihood that the memory cells are read properly. In some examples, the memory device may store an indication that the complement of the detected logic state was written, which may correspond to one memory cell or a set of memory cells. In some examples, a memory device may be configured to identify conditions associated with an erasure, or an otherwise indeterminate logic state, which may be used to enhance aspects of error handling operations, including those that may be performed at the memory device or a host device (e.g., error handling operations performed at a memory controller external to the memory device).
