Notes
19.Power up: Assumes a linear ramp from 0V to VDD(min) within 200 ms. During this time VIH < VDD and VDDQ < VDD.
20.Output are impedance controlled. IOH = −(VDDQ/2)/(RQ/5) for values of 175 ohms <= RQ <= 350 ohms.
21.Output are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175 ohms <= RQ <= 350 ohms.
22.VREF (min) = 0.68V or 0.46VDDQ, whichever is larger, VREF (max) = 0.95V or 0.54VDDQ, whichever is smaller.
23.The operation current is calculated with 50% read cycle and 50% write cycle.
