DDR2-400, 533
Single Rank, x8 Registered SDRAM DIMMs
Absolute Maximum Ratings:
Exposure to stresses greater than these absolute maximum rating conditions for extended periods may affect
reliability of the module.

NOTE:
1.
VDD and VDDQ must keep track of each other. VDDQ cannot exceed the value of VDD
2. VREF is expected to equal VDDQ/2 of the transmitting device and to track variations in the DC level of the same
3. TT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to
V
be set equal to VREF and must track variations in the DC level of VREF
4. VDDQ must tracks VDD; and VDDL tracks VDD
Input/Output Capacitance:
VDD = +1.8V ± 0.1V, VDDQ = +1.8V ± 0.1V, VREF = VSS, f =100MHz, 0°C<TOPR <+55°C, VOUT(DC) = VDDQ/2
