Abstract
A method of operating a memory device may include receiving, during each phase of a row hammer refresh (RHR) interval, at least one row hammer address (RHA) of a content addressable memory (CAM). The method may further include storing, during each phase of the RHR interval, a received RHA of the at least one received RHA in an address register. Moreover, the method may include refreshing each stored RHA of the CAM via a RHR during the RHR interval. Semiconductor devices and an electronic system are also described.
