Parameter
Vdd supply voltage
Termination reference current from Vtt
Termination reference voltage (DC) –
command/address bus
Input leakage current;
Any input 0V ≤ Vin ≤
Vdd; Vref input 0V ≤ Vin
≤ 0.95V (All other pins
not under test = 0V)
Output leakage current;
0V ≤ Vout ≤ Vddq; DQ
and ODT are disabled;
ODT is HIGH
Vref supply leakage current; VrefDQ =
Vdd/2 or VrefCA = Vdd/2 (All other pins
not under test = 0V)

Parameter
Vdd supply voltage relative to Vss
Voltage on any pin relative to Vss
Notes:
Stresses greater than those listed may cause permanent damage to the module. This is a
stress rating only, and functional operation of the module at these or any other condi-
tions outside those indicated in each device’s data sheet is not implied. Exposure to
absolute maximum rating conditions for extended periods may adversely affect reliability.
1. Vtt termination voltage in excess of the stated limit will adversely affect the command
