2) Input slew rate
≥
1 V/ns for DDR400, DDR333
3) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference level for signals
other than CK/CK, is
V
REF
. CK/CK slew rate are
≥
1.0 V/ns.
4) Inputs are not recognized as valid until
V
REF
stabilizes.
5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is
V
TT
.
6) For each of the terms, if not already an integer, round to the next highest integer.
t
CK
is equal to the actual system clock cycle time.
7)
t
and
t
transitions occur in the same access time windows as valid data transitions. These parameters are not referred to a specific
voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ).
8) Fast slew rate
≥
1.0 V/ns , slow slew rate
≥
0.5 V/ns and < 1 V/ns for command/address and CK & CK slew rate > 1.0 V/ns, measured
between
V
IH(ac)
and
V
IL(ac)
.
9) These parameters guarantee device timing, but they are not necessarily tested on each device.
10) A maximum of eight Autorefresh commands can be posted to any given DDR SDRAM device.
