Note:
1. Parameters depend on programmed CAS latency.
2. If clock rising time is longer than 1ns. (tr/2 - 0.5) ns should be considered.
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.
