CAH
are referenced to the earlier CAS falling edge.
t
CP
is specified from the last CAS rising edge in the previous cycle to the first CAS falling edge in the next cycle.
t
CWD
is referenced to the later CAS falling edge at word read-modify-write cycle.
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.
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.
