1 V/ns for DDR400, DDR333
3) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference
level for signals other than CK/CK, is
V
REF
. CK/CK slew rate are
≥
1.0 V/ns.
4) Inputs are not recognized as valid until

stabilizes.
5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is
V
TT
.
6) These parameters guarantee device timing, but they are not necessarily tested on each device.
