timing
Rev. ID EMRS to DQ on timing
REV. ID EMRS to DQ off timing
1) At 1000 MHz speed grade only 1-CS mode is supported
2) DLL on mode
3) Timing is calculated for a clock frequency of 700 MHz
4)
t
HP
is the lesser of
t
CL
minimum and
t
CH
minimum actually applied to the device CLK, CLK inputs
5) This value of
t
MRD
applies only to the case where the "DLL reset"’ bit is not activated.
6)
t
MRD
is defined from MRS to any other command then READ.
7)
t
RAS,max
is 8
×
t
REFi
8)
t
CCD
is either for gapless consecutive reads or gapless consecutive writes.
9) WTR and
t
WR
start at the first rising edge of CLK after the last valid (falling) WDQS edge of the slowest WDQS signal.
10) WTR and
t
WR
start at the first rising edge of CLK after the last valid (falling) WDQS edge of the slowest WDQS signal.
11) This parameter is defined for commands issued to rank m following rank n where m
≠
n. For all other type of access, standard timing
parameters do apply.
12) Please round up
t
RTW
to the next integer of
t
CK
.
13) This parameter is defined per byte
