Abstract
Methods, systems, and devices for temperature-dependent refresh operations are described. A memory system may adjust refresh operations based on a temperature of the memory system to reduce a refresh current and improve reliability of the refresh operations. For example, the memory system may include a temperature sensor configured to provide temperature information associated with a memory device. Based on the temperature information, the memory system may, in response to a refresh command, activate a set of access lines (e.g., word lines) to refresh memory cells coupled with the access lines, where a count of the set of access lines (e.g., how many access lines are included in the set) may be based on the temperature information. In some examples, the count of the set may be determined based on comparing the temperature information to one or more temperature thresholds.
