VDD and VDDQ must be within 300mV of each other at all times; and VREF must not be greater than
0.6XVDDQ,When VDD and VDDQ are less than 500mV; VREF may be equal to or less than 300mV.
ment conditions, please refer to the JEDEC document JESD51-2.

also possible to specify a component with 1X refresh (tREFI to 7.8µs) in the Extended Temperature Range.
Please refer to the DIMM SPD for option availability
If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use
the Manual Self-Refresh mode with Extended Temperature Range capability (MR2 A6 = 0b and MR2 A7 = 1b)
or enable the optional Auto Self-Refresh mode (MR2 A6 = 1b and MR2 A7 = 0b).
