Notes:

1. H: HIGH level input, L: LOW level input, X: HIGH or LOW level input

2. The CLK pin and the other input are reactivated asynchronously by the transition of the CKE level from LOW to HIGH.

The minimum setup time (tCKA) required before all commands other than mode termination must be satisfied.

3. Both banks must be set to the inactive (idle) state in advance to switch to power-down mode or self-refresh mode.

4. The input must be command defined in the operation command table.
