Patent number: 12183386Abstract: The present disclosure generally relates to aligning non-aligned data for more efficient data reading. Data for write commands does not always perfectly align, yet the data is written in order of write command receipt. In such cases, aligned chunks of data may be split into two word lines (WLs) due to the presence of previously received smaller chunks of data. Rather than writing the data in order, the smaller chunks of data, which are non-aligned, are held in a buffer and written later to ensure that any aligned chunks of data remain aligned when written to the memory device. Once sufficient smaller chunks or data have accumulated to be aligned, or upon a need to write the smaller chunks upon reaching a threshold, the smaller chunks are written together in a single WL so as to not cause non-alignment of aligned data.Type: GrantFiled: September 6, 2022Date of Patent: December 31, 2024Assignee: Sandisk Technologies, Inc.Inventors: Alexander Bazarsky, Judah Gamliel Hahn, Michael Ionin
