Abstract
Methods, systems, and devices for refresh command management are described. A memory device may conduct a refresh operation to preserve the integrity of data stored to one or more memory cells. In some examples, the frequency of refresh operations conducted may be based on the memory device's temperature and may be initiated based on one or more commands received from an external device (e.g., a host device). Each command may be transmitted by the host device at a defined rate, which may impact the rate at which the memory device conducts one or more refresh operations. The memory device may postpone or skip at least a portion of one or more refresh operations based on one or more operating parameters of the memory device.
