Methods, systems, and devices for data block refresh during read access are described. In some instances, when an access command (e.g., a read command) is received, a memory system may determine if the associated block is a PSA block. If the block is PSA block, its data may be provided to a host system to satisfy the read command and the block may either be refreshed or may be designated to be refreshed. For example, the block may be refreshed by copying its data to a write cache and writing the data from the cache to a new block. In other instances, an LBA of the block may be stored (e.g., designated) and the LBA may be refreshed when the memory system is idle.
