Notes: 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.
