Notes: 1. IDD depends on output load condition when the device is selected. IDD (max.) is specified at the output
open condition.
2. One bank operation.
3. Input signals are changed once per one clock.
4. Input signals are changed once per two clocks.
5. Input signals are changed once per four clocks.
6. After power down mode, CLK operating current.
7. After power down mode, no CLK operating current.
8. Input signals are VIH or VIL fixed.
