1)
2) Timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must be powered down
3) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
4) 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,

7) For each of the terms, if not already an integer, round to the next highest integer.
8) The clock frequency is allowed to change during self-refresh mode or precharge power-down mode.
9) For timing definition, refer to the Component data sheet.
