t
CWL
is specified from W falling edge to the earlier CAS rising edge.
t
CSR
is referenced to earlier CAS falling before RAS transition low.
t
CHR
is referenced to the later CAS rising high after RAS transition low.
t
DS
is specified for the earlier CAS falling edge and
t
DH
is specified by the later CAS falling edge in early write cycle.
If RAS goes high before CAS high going, the open circuit condition of the output is achieved by CAS high going.
t
ASC
≥
6ns, Assume t
T
=2.0ns, if t
ASC
≤
6ns, then t
HPC
(min) and t
CAS
(min) must be increased by the value of "6ns-t
ASC
".
If
t
RASS
≥
100us, then RAS precharge time must use
t
RPS
instead of
t
RP
.
For RAS-only-Refresh and Burst CAS-before-RAS refresh mode, 4096 cycles(4K/8K) of burst refresh must be executed within
64ms before and after self refresh, in order to meet refresh specification.
For distributed CAS-before-RAS with 15.6us interval, CBR refresh should be executed with in 15.6us immediately before and
after self refresh in order to meet refresh specification.
