This chapter contains the AC characteristics.
3.3.1
All Speed grades faster than DDR2-400B comply with DDR2-400B timing specifications(
1) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
2) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,
3) Inputs are not recognized as valid until
4) The output timing reference voltage level is
