Notes
15.Power up: Is based on a linear ramp from 0V to VDD(min) within 200 ms. During this time VIH < VDD and VDDQ < VDD.
16.Outputs are impedance controlled. IOH = –(VDDQ/2)/(RQ/5) for values of 175Ω < RQ < 350Ω.
17.Outputs are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175Ω < RQ < 350Ω
18.VREF (min) = 0.68V or 0.46VDDQ, whichever is larger, VREF (max) = 0.95V or 0.54VDDQ, whichever is smaller.
19.The operation current is calculated with 50% read cycle and 50% write cycle.
