The current needs to be calculated according to the different chips used and the number of chips. Since the current of DDR is generally relatively large, when PCB design, if a complete power supply plane is laid on the pins, it is the most ideal state, and the energy storage capacitor is increased at the power inlet, and one is added to each pin. Filter with a small capacitor of 100nF~10nF.
