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 one 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 are V

fixed.

8. Input signals are changed once per four clocks.

9. After self refresh mode set, self refresh current. Self refresh should only be used at temperatures below 70

°C.
