Abstract:
A highly read data manager of a memory device receives a request to perform receives a request to perform a data relocation operation on a first wordline of a plurality of wordlines for a memory device, the memory device comprising a plurality of multi-level memory cells, wherein each multi-level memory cell comprises a plurality of pages; determines at the first wordline comprises data stored at one or more high read disturb pages of the plurality of pages; determines whether the data comprises a characteristic that satisfies a threshold criterion in relation to additional data stored on additional wordlines of the plurality of wordlines; responsive to determining that the data comprises the characteristic that satisfies the threshold criterion, identifies one or more low read disturb pages of the plurality of pages of a target wordline for relocating the data; and responsive to identifying the one or more low read disturb pages of the target wordline, stores at least a portion of the data at the one or more low read disturb pages of the target wordline.
