Parameter
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.
1. Rise time specification based on 0pF + 50 Ω to V
2. Fall time specification based on 0pF + 50 Ω to V
3. Measured into 50pF only, use these values to characterize to.
4. All measurements done with respect to V
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.
