9.7.1 Output Drive Temperature and Voltage sensitivity
If temperature and/or voltage change after calibration, the tolerance limits widen according to table 23 and 24.
∆T = T - T(@calibration); ∆V = V

[ Table 24 ] Output Driver Voltage and Temperature Sensitivity
9.8 On-Die Termination (ODT) Levels and I-V Characteristics
ODT is applied to the DQ,DM, DQS/DQS and TDQS,TDQS (x8 devices only) pins.
A functional representation of the on-die termination is shown below. The individual pull-up and pull-down resistors (RTTpu and RTTpd) are defined as
follows :
On-Die Termination effective resistance RTT is defined by bits A9, A6 and A2 of MR1 register.
