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 ab-
solute 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
and address signals’ voltage margin and will reduce timing margins.
Notes:
2. TA and TC are simultaneous requirements.
3. For further information, refer to technical note TN-00-08: “Thermal Applications,”
available on Micron’s Web site.
4. The refresh rate is required to double when 85°C < TC ≤ 95°C.
5. Inputs are terminated to VDD/2. Input current is dependent on terminating resistance se-
lected in register.
