Abstract: Methods, systems, and devices for a corrective read of a memory device with reduced latency are described. A memory system may identify a read error based on accessing a memory device, and may select a trim setting for a performing a corrective read operation based on a data retention condition associated with the accessed memory device. Such a data retention condition may be associated with a data retention duration, or a cross-temperature condition, among other criteria or combinations thereof. In some implementations, the memory system may select from a subset of possible trim settings, which may be associated with relevant process corners. For example, the memory system may select between a first trim setting that is associated with a relatively large cross-temperature and a relatively short data retention duration and a second trim setting that is associated with a relatively small cross-temperature and a relatively long data retention duration.
