1. ICC1 depends on output load conditions when the device is selected. ICC(max) is specified with the output open.
2. One Bank operation.
3. Input signals are changed once per one clock.
4. After power down mode, CLK operating current.
5. Afer power down mode, no CLK operating current.
6. Input signals are changed once per two clocks.
7. Input signals are VIH or VIL fixed.
8. Input signals are changed once per four clocks.
9. After self refresh mode set, self refresh current. Use self reset only at temperatures below 70°C
