Average Periodic Refresh Interval
1) 0 °C ≤
2) Input slew rate ≥ 1 V/ns for DDR266, and = 1 V/ns for DDR200
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
4) Inputs are not recognized as valid until
5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is
6) These parameters guarantee device timing, but they are not necessarily tested on each device.
