Abstract: Methods, systems, and devices for determining offsets for memory read operations are described. In response to a threshold quantity of pages failing initial reads but being successfully read using a same reference adjustment during re-reads, the offset responsible for the adjustment may be used as a first-applied offset for subsequent re-reads or a baseline offset for subsequent initial reads. After the initial reads begin using the reference adjustment, if a threshold quantity of pages fail initial reads, the offset used for the initial read may be adjusted to be the offset used to perform the successful re-reads. If an updated offset to use a baseline is not identified, the baseline offset may be cleared so the original reference may again be used without adjustment for initial reads.
