Note: 1. DDR2 SDRAM component specification.
Caution Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.

Notes: 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

VDDQ of the transmitting device and VREF are expected
to track variations in VDDQ.
2. Peak to peak AC noise on VREF may not exceed
±
2% VREF (DC).
3. VTT of transmitting device must track VREF of receiving device.
4. VDDQ must be equal to VDD.
