Notes
3. These parameters depend on the cycle rate and these values are measured at 133 MHz for -7.5,
and at 100 MHz for -8 components. Input signals are changed once during
t
CK
, excepts for
I
CC6
and for standby currents when
t
CK
= infinity.
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
V
DDQ
current is excluded.
