Rev. 1.1/Apr.01
Notes : 1. I
CC
depends on output load condition when the device is selected. I
CC (
max) is specified at the
output open condition.
2. One bank operation.
3. Addresses are changed once per one cycle.
4. Addresses are changed once per two cycles.
5. After Power down mode, CLK operating current.
6. After Power down mode, no CLK operating current.
7. After self refresh mode set, self refresh current.
8. L-Version.
