1. An apparatus, comprising: a controller associated with a memory device, wherein the controller is configured to cause the apparatus to:
programming, at a memory system, data to a set of blocks of the memory system, wherein an order in which the data be programmed to respective blocks of the set of blocks is based at least in part on a first block ordering, and wherein programming the data to the set of blocks comprises programming respective indications of respective temperatures of the programming for the respective blocks;
identify, during a start-up procedure, a flag indicating to perform a refresh operation for the set of blocks; and
perform, during the start-up procedure based at least in part on the flag, the refresh operation for the set of blocks using a second block ordering that is based at least in part on the respective indications of the respective temperatures for the set of blocks.
