Abstract
A system and method for performing a low overhead refresh management of a memory device. The method includes receiving, by a controller from a dynamic random access memory (DRAM) device via a feedback interface, a signal indicative of an occurrence of a row hammer event. The method includes determining, by the controller based on the signal, whether to schedule a refresh event. The method includes sending, by the controller responsive to determining whether to schedule the refresh event, a first command to the DRAM device to execute a refresh operation.
