摘要： A processing device in a memory sub-system initiates a partial block handling protocol for a closed block of a memory device. The block includes a plurality of wordlines. The processing device further sends a first programming command to the memory device to program one or more wordlines of the block with first padding data. The one or more wordlines are adjacent to a last wordline of the block programmed before the block was closed. In addition, the processing device sends a second programming command to the memory device to concurrently program a remaining set of the plurality of wordlines of the block to a threshold voltage.

摘要： Data to be stored at a memory sub-system can be received from a host system. A portion of the host data that includes user data and another portion of the host data that includes system metadata can be determined. A mapping for a data structure can be received that identifies locations of the data structure that are fixed with respect to an encoding operation and locations of the data structure that are not fixed with respect to the encoding operation. The data structure can be generated for the user data and system metadata based on the mapping, and an encoding operation can be performed on the data structure to generate a codeword.

摘要： A system and method for measuring the degradation of one or more memory devices of a memory sub-system. An example system including a memory controller operatively coupled with a memory device and configured to perform operations comprising: testing different values for a setting of the memory device, wherein the setting of the memory device affects a duty cycle of a signal internal to the memory device; selecting an optimum value for the setting based on access errors during the testing, wherein the optimum value minimizes access errors; determining a degradation measurement for the memory device based on the optimum value; and providing a notification to a host system based on the degradation measurement.

摘要： A media management operation can be performed at a memory sub-system at a current frequency. An operating characteristic associated with the memory sub-system can be identified. The operating characteristic can reflect at least one of a write count, a bit error rate, or a read-retry trigger rate. A determination can be made as to whether the identified operating characteristic satisfies an operating characteristic criterion. In response to determining that the operating characteristic satisfies the characteristic criterion, the media management operation can be performed at a different frequency relative to the current frequency.

摘要： A plurality of memory device life metrics are determined, where one of the plurality of memory device life metrics comprises a read count metric that specifies a number of read operations performed on the memory device. A plurality of normalized metric values are calculated, where each of the normalized metric values is based on a ratio of a respective memory device life metric to a respective lifetime target value associated with the respective memory device life metric. A normalized metric value that satisfies a selection criterion is identified from the plurality of normalized metric values. The identified normalized metric value corresponds to an amount of used device life of the memory device. An amount of remaining device life of the memory device is determined based on the identified normalized metric value. An indication of the amount of remaining device life is provided to a host system.
