Only one of the following two conditions must be met.
• No power sequencing is specified during power up or power down given the following
criteria:
VDD and VDDQ are driven from a single power converter output
VTT meets the specification
A minimum resistance of 42 ohms limits the input current from the VTT supply into
any pin and VREF tracks VDDQ /2 or The following relationships must be followed:
VDDQ is driven after or with VDD such that VDDQ < VDD + 0.3V
VTT is driven after or with VDDQ such that VTT < VDDQ + 0.3V
VREF is driven after or with VDDQ such that VREF < VDDQ + 0.3V
