Notes:
23.Unless otherwise noted, test conditions assume signal transition time of 2V/ns, timing reference levels of 0.75V,VREF = 0.75V, RQ = 250Ω, VDDQ = 1.5V, input
pulse levels of 0.25V to 1.25V, and output loading of the specified IOL/IOH and load capacitance shown in (a) of AC Test Loads.
24.This part has a voltage regulator that steps down the voltage internally; tPower is the time power needs to be supplied above VDD minimum initially before a Read
or Write operation can be initiated.
25.At any given voltage and temperature tCHZ is less than tCLZ and, tCHZ less than tCO.
26.tCHZ, tCLZ, are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 100 mV from steady-state voltage.
