  • Patent number: 10877679
    Abstract: The present disclosure relates to partially written block treatment. An example method comprises maintaining, internal to a memory device, a status of a last written page corresponding to a partially written block. Responsive to receiving, from a controller, a read request to a page of the partially written block, the example method can include determining, from page map information maintained internal to the memory device and from the status of the last written page, which of a number of different read trim sets to use to read the page of the partially written block corresponding to the read request.

  • Patent number: 10854305
    Abstract: An indication of an initialization of power to a memory component can be received. In response to receiving the indication of the initialization, a last written page of a data block of the memory component can be identified. The last written page is associated with a status indicator. A determination is made of whether the status indicator is readable. Responsive to determining that the status indicator readable, it can be determined that programming of data to the data block of the memory component did complete and there is a data retention loss.

  • Publication number: 20200250028
    Abstract: A memory device that has been programmed to store a single bit or multiple bits can perform a determination of a number of threshold voltages in one or more threshold voltage level regions. Based on the number of threshold voltages meeting or exceeding a threshold level, a page of bits can be read and if the bit error rate of the page of bits is below a threshold rate, the page of bits can be stored in the cells together with other bits stored in the cells and a provided additional page of bits. However, if the bit error rate of the page of bits is at or above the threshold rate, then the bit or bits stored in the cells can be error corrected and stored together with a provided additional page of bits.

  • Patent number: 10671479
    Abstract: A memory device includes a memory array that includes a buffer data. The memory device also includes a memory controller. The memory controller includes an error correction code (ECC) component. The memory controller further receives a status command and an indication related to the quality of the data to analyze with the ECC component. Based on a status value, the memory controller utilizes one of a plurality of error correction techniques via the ECC component to correct an error (e.g., soft state, calibration, etc.).

In response to receiving the indication of the initialization, a last written page of a data block of the memory component can be identified. The last written page is associated with a status indicator. A determination is made of whether the status indicator can be read. Responsive to determining that the status indicator cannot be read, it can be determined that programming of data to the data block of the memory component did not complete based on a prior loss of power to the memory component.
