1) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew  
Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended mode.  
2) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,  
input reference level is the crosspoint when in differential strobe mode.  
3) Inputs are not recognized as valid until VREF stabilizes. During the period before VREF stabilizes, CKE = 0.2 x VDDQ is recognized as low.  
4) The output timing reference voltage level is VTT  
.
5) RAS.MAX is calculated from the maximum amount of time a DDR2 device can operate without a refresh command which is equal to 9 x tREFI  
t
