Abstract

Refresh commands may be provided at random intervals from a memory controller to a memory device. In some examples, refresh requests may be provided at random intervals which may be used to provide refresh commands from the memory controller to the memory device at random intervals. In some examples, an average time interval between refresh requests may be equal to a refresh interval of the memory device. In some examples, a maximum number of times the memory controller may postpone providing a refresh command to the memory device may be a random number. In some examples, a maximum value of the random number may be based, at least in part, on a minimum number of refresh commands required within a time interval by the memory device.
