TABLE 16
Programmed Driver IV Characteristics at 40 Ohm
5.7.2
Termination IV Characteristic at 60 Ohms
Figure 17
represents the DQ termination Pull-Up IV characteristic under process, voltage and temperature best and worst case
conditions. The actual DQ termination Pull-Up current must lie between these two bounding curves. The value of the external
ZQ resistor is 240
Ω
, setting the nominal DQ termination impedance to 60
Ω
. (Extended Mode Register programmed to ZQ/4).
