*All AC parameters are measured from half to half.

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.
