Abstract
Apparatuses, systems, and methods for refresh rate register adjustment based on a targeted refresh queue. A memory includes a temperature sensor which measures a temperature of the memory. The memory also includes a targeted refresh queue which stores identified aggressor addresses. A value of a refresh rate register is set based on both the measured temperature and the number of addresses in the queue. A controller of the memory reads the value of the refresh rate register and provides a refresh signal with timing based on the refresh rate register. In some embodiments, a ratio of targeted and normal refresh operations is adjusted based on how many addresses are in the targeted refresh queue.
