January 2006

Mobile SDRAM

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.
