Abstract: A memory apparatus includes a memory device, a memory controller and a memory physical layer interface. The memory physical layer interface comprises a multi-tap decision feedback equalization (DFE) receiver and a tap reset circuit. The tap reset circuit generates a pulse signal and a reset signal in accordance with a gap interval between read bursts to reset a DFE taps of the multi-tap DFE receiver during the gap interval between the read bursts. The tap reset circuit resets the plurality of DFE taps using the pulse signal in response to determining that the gap interval between read bursts is a first predetermined interval. The tap reset circuit resets the plurality of DFE taps of the multi-tap DFE receiver using the reset signal in response to determining that the gap interval between read bursts is a second predetermined interval. The second predetermined interval is greater than the first predetermined interval.
