Original Abstract Submitted
Methods, systems, and devices for coding to decrease error rate discrepancy between pages are described. For example, to identify a unit-distance code for operating a memory device, voltage drifts of a set of read voltages after a duration may be identified and each of the read voltages may be mapped to one of a set of pages of the memory cell using various possible unit-distance codes. Thus, for each unit-distance code the set of pages may be associated with respective subsets of the set of read voltages. Then, for each unit-distance code a set of average read voltage drifts corresponding to one of the set of pages may be identified. The memory device may be operated using a unit-distance code associated with a smaller range of the set of average read voltage drifts than ranges of sets of average read voltage drifts associated with other unit-distance codes.
