20.Data output turns off and becomes high impedance from ater rising edge of
RAS
and
CAS
. Hold
time and turn off time are specified by the timing specifications of later rising edge of
RAS
and
CAS
between t
OHR
and t
OH
and between t
OFR
and t
OFF
.
21.Please do not use t
RASS
timing, 10 μs
≤
t
RASS
≤
100 μs. During this period, the device is in transition
state from normal operation mode to self refresh mode. If t
RASS
≥
100 μs, then
RAS
precharge time
should use t
RPS
instead of t
RP
.
22.If you use
RAS
only refresh or CBR burst refresh mode in normal read/write cycles, 2048 cycles of
distributed CBR refresh with 15.6 μs interval should be executed within 32 ms immediately after
exiting from and before entering into the self refresh mode.
23.If you use distributed CBR refresh mode with 15.6 μs interval in normal read/write cycle, CBR
refresh should be executed within 15.6 μs immediately after exiting from and before entering into
self refresh mode.
24.Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from self
fresh mode, all memory cells need to be refreshed before re-entering the self refresh mode again.
