Notes

17.Power up: Is based on a linear ramp from 0V to VDD(min) within 200 ms. During this time VIH < VDD and VDDQ < VDD.

18.Output are impedance controlled. IOH = −(VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ω.

19.Output are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ω.

20.VREF(min) = 0.68V or 0.46VDDQ, whichever is larger, VREF(max) = 0.95V or 0.54 VDDQ, whichever is smaller.

21.The operation current is calculated with 50% read cycle and 50% write cycle.
