There is no specific device VCC supply voltage requirement for SSTL-1.8 compliance. However under all conditions VCCQ must be less than or equal to VCC
1. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically the value of VREF is expected to be about 0.5 x VCCQ of the transmitting
device and VREF is expected to track variations in VCCQ
2. Peak to peak AC noise on VREF may not exceed +/-2% VREF(DC).
3. TT of transmitting device must track VREF of receiving device.
4. AC parameters are measured with VCC, VCCQ and VCCDL tied together.

5. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
6. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard.
