ESMT
AC CHARACTERISTICS (AC operating conditions unless otherwise noted)
Note: 1.Parameters depend on programmed CAS latency.
Elite Semiconductor Memory Technology Inc.
CLK cycle time
CLK to valid
output delay
CLK to output in
Hi-Z
Output data hold time
CLK high pulse width
CLK low pulse width
Input setup time
Input hold time
CLK to output in Low-Z
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.
