Notes:
3. These parameters depend on the cycle rate. All values are measured at 166 MHz for “-6”, at 133 MHz for
“-7” and “-7.5” and at 100 MHz for “-8” components with the outputs open. Input signals are changed once
during tck.
4. These parameters are measured with continuous data stream during read access and all DQ toggling. CL=3
and BL=4 is assumed and the VDDQ current is excluded.
