HY5S6B6D(L/S)F(P)-xE
4Banks x 1M x 16bits Synchronous DRAM
AC CHARACTERISTICS I
(AC operating conditions unless otherwise noted)
Note :
1. Assume t
R
/ t
F
(input rise and fall time) is 1ns. If t
R
& t
F
> 1ns, then [(t
R
+t
F
)/2-1]ns should be added to the parameter.
2. Access time to be measured with input signals of 1V/ns edge rate, from 0.8V to 0.2V. If t
R
> 1ns,
then (t
R
/2-0.5)ns should be added to the parameter.
