2. One bank operation.
3. One bank active.
4. All banks idle.
5. Command/Address transition once per one clock cycle.
6. DQ, DM and DQS transition twice per one clock cycle.
7. 4 banks active. Only one bank is running at tRC = tRC (min.)
8. The IDD data on this table are measured with regard to tCK = tCK (min.) in general.
9. Command/Address transition once every two clock cycle.
10. Command/Address stable at ≥ VIH or ≤ VIL.
