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.

2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.
5. For -55/60/70/80/10, tRDL=1CLK product can be supported within restricted amounts and it will be distinguished by bucket
code "NV". From the next generation, tRDL will be only 2CLK for every clock frequency.
6. A new command should be issued after self refersh exit followed by tRFC.
