Note :
1. Stress greater than those listed may cause permanent damage to the device. This is a stress rating only, and device
functional operation at or above the conditions indicated is not implied. Expousure to absolute maximum rating con
ditions for extended periods may affect reliablility.
2. Up to 9850 ft.
3. If the DRAM case temperature is Above 85^oC, the Auto-Refresh command interval has to be reduced to
tREFI=3.9us. For Measurement conditions of T_CASE, please refer to the JEDEC document JESD51-2.

Note:
1. Min. Typ. and Max. values increase by 100mV for C3(DDR2-533 3-3-3) speed option.
2. VDDQ tracks with VDD,VDDL tracks with VDD. AC parameters are measured with VDD,VDDQ and VDD.
3. 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 VDDQ of the transmitting device and VREF is expected to track vari-
ations in VDDQ.
4. Peak to peak ac noise on VREF may not exceed +/-2% VREF (dc).
5. VTT of transmitting device must track VREF of receiving device.
