1. I_CC1 depends on output load conditions when the device is selected. I_CC1(max) is specified with the output open.
2. One Bank Operation
3. Input signals are changed once per clock.
4. After power down mode, CLK operating current.
5. After power down mode, no CLK operating current.
6. Input signals are changed once per two clocks.
7. Input signals for V_IH or V_IL are fixed.
8. Input signals are changed once per four clocks.
9. After self refresh mode set, self refresh current.
10.Use Self Refresh for temperatures less than 70 °C ONLY.
