Note:
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns,(tr/2-0.5)ns should be added to the parameter.
3. Assumed input rise and fall time (tr & tf)=1ns.
If tr & tf is longer than 1ns,transient time compensation should be considered,
i.e.,[(tr+tf)/2-1]ns should be added to the parameter.
