Minimum clock cycles = (Minimum time / clock cycle time) rounded up.
Minimum delay required to complete write.
Column address change allowed every cycle.
Parameters dependent on CAS latency.
If clock rising time
>
1ns, (tr/2-0.5)ns should be added to parameter.
If (tr and tf)
>
1ns, [(tr+tf)/2-1]ns should be added to parameter.
Outputs measured at 1.5V with 50pF load only without resistive termination.
