Abstract
Within an integrated circuit comprising a memory controller, a method can include, responsive to determining that the memory controller is performing a refresh operation, calculating a new tap setting according to a new maximum value and an old tap setting of the delay circuit. The new maximum value specifies a number of taps of the delay circuit that approximates a predetermined time span. The method can include dynamically adjusting a delay applied to a signal by a delay circuit according to the new tap setting. The delay circuit generates a delayed signal that is provided to the memory controller.
