10.4 Slew Rate Definition for Single Ended Input Signals
See "Address / Command Setup, Hold and Derating" for single-ended slew rate definitions for address and command signals.
See "Data Setup, Hold and Slew Rate Derating" for single-ended slew rate definitions for data signals.
10.5 Slew rate definition for Differential Input Signals
Input slew rate for differential signals (CK, CK and DQS, DQS) are defined and measured as shown in below.
[ Table 8 ] Differential input slew rate definition
NOTE : The differential signal (i.e. CK - CK and DQS - DQS) must be linear between these thresholds
