TIMING REQUIREMENTS (For Read, Write, Refresh, and Hyper-Page Mode Cycles)
(Ta=0 ~ 70°C, Vcc = 5V ± 10%, Vss=0V, unless otherwise noted See notes 14,15)
Note 14: The timing requirements are assumed t
T
=3ns.
15: V
IH(min)
and V
IL(max)
are reference levels for measuring timing of input signals.
16: t
RCD(max)
is specified as a reference point only. If t
RCD
is less than t
RCD(max),
access time is t
RAC.
If t
RCD
is greater than t
RCD(max),
access
time is controlled exclusively by t
CAC
or t
AA.
17: t
RAD(max)
is specified as a reference point only. If t
RAD
t
RAD(max)
and t
ASC
t
ASC(max),
access time is controlled exclusively by t
AA.
18: t
ASC(max)
is specified as a reference point only. If t
RCD
t
RCD(max)
and t
ASC
t
ASC(max),
access time is controlled exclusively by t
CAC.
19: t
T
is measured between V
IH(min)
and V
IL(max).
Read and Refresh Cycles
Note 20: Either t
RCH
or t
RRH
must be satisfied for a read cycle.
Parameter
Refresh cycle time
RAS high pulse width
Delay time, RAS low to CAS low
Symbol
Delay time, CAS high to RAS low
Delay time, RAS high to CAS low
