14.0 AC CHARACTERISTICS
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.
4. tSS applies for address setup time, clock enable setup time, commend setup time and data setup time
REFER TO THE INDIVIDUAL COMPONENET, NOT THE WHOLE MODULE.

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.
tSH applies for address holde time, clock enable hold time, commend hold time and data hold time
