Methods, systems, and devices for techniques for accessing managed not-AND (NAND) memory are described. An indicator of a first type that indicates whether each physical address in a group of physical addresses stores valid data may be accessed. Indicators of a second type may be used to indicate whether respective physical addresses of the group of physical addresses store valid data. Data stored at the group of physical addresses may be transferred to a different group of physical addresses based on the indicator of the first type. Also, another indicator of the first type that indicates whether each physical address in the different group of physical addresses stores valid data may be updated.
