Notes:
1.
The specified values are valid when addresses are changed no more than once during t
CK
(min.) and when No
Operation commands are registered on every rising clock edge during t
RC
(min). Values are shown per module
bank.
2.
The specified values are valid when data inputs (DQ
’
s) are stable during t
RC
(min.).
3.
All AC characteristics are shown for device level.
An initial pause of 100
μ
s is required after power-up, then a Precharge All Banks command must be given followed
by 8 Auto Refresh (CBR) cycles before the Mode Register Set Operation can begin.
4.
AC timing tests have V
IL
= 0.4V and V
IH
= 2.4V with the timing referenced to the 1.4V crossover point. The transition
time is measured between V
IH
and V
IL
. All AC measurements assume t
T
= 1 ns with the AC output load circuit
shown. Specific tac and toh parameters are measured with a 50 pF only, without any resistive termination and with
a input signal of 1V / ns edge rate between 0.8V and 2.0V.
5.
If clock rising time is longer than 1 ns, a time (t
T
/2 -0.5) ns has to be added to this parameter.
6.
Rated at 1.5V
7.
If t
T
is longer than 1 ns, a time (t
T
-1) ns has to be added to this parameter.
8.
Any time that the refresh Period has been exceeded, a minimum of two Auto (CBR) Refresh commands must be
given to
“
wake-up
”
the device.
9.
Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high.
Self Refresh Exit is not complete until a time period equal to t
RC
is satisfied once the Self Refresh Exit command
is registered.
10.
Referenced to the time which the output achieves the open circuit condition, not to output voltage levels.
