NOP commands are shown for ease of illustration; other commands may be valid at these times.
The BL8 setting is activated by either MR0[1, 0] = 0, 0 or MR0[0, 1] = 0, 1 and A12 = 1 during READ command at T0.
DO n = data-out from column n.
BL8, RL = 5 (AL = 0, CL = 5).
Output timings are referenced to VCCQ/2 and DLL on and locked.
t DQSQ defines the skew between DQS, DQS# to data and does not define DQS, DQS# to clock.
Early data transitions may not always happen at the same DQ. Data transitions of a DQ can vary (either early or late)
within a burst.

Notes:
T1
1. Within a burst, the rising strobe edge is not necessarily fixed at t DQSCK (MIN) or t DQSCK
(MAX). Instead, the rising strobe edge can vary between t DQSCK (MIN) and t DQSCK (MAX).
2. The DQS high pulse width is defined by t QSH, and the DQS low pulse width is defined by
t QSL. Likewise, t LZ (DQS) MIN and t HZ (DQS) MIN are not tied to t DQSCK (MIN) (early strobe
case) and t LZ (DQS) MAX and t HZ (DQS) MAX are not tied to t DQSCK (MAX) (late strobe
case); however, they tend to track one another.
3. The minimum pulse width of the READ preamble is defined by t RPRE (MIN). The minimum
pulse width of the READ postamble is defined by t RPST (MIN).

1. NOP commands are shown for ease of illustration; other commands may be valid at these
times.
2. The BL8 setting is activated by either MR0[1:0] = 00 or MR0[1:0] = 01 and A12 = 1 during the
WRITE command at T0.
3. DI n = data-in for column n.
4. BL8, WL = 5 (AL = 0, CWL = 5).
5. t DQSS must be met at each rising clock edge.
6. t WPST is usually depicted as ending at the crossing of DQS, DQS#; however, t WPST actually
ends when DQS no longer drives LOW and DQS# no longer drives HIGH.

LOGIC Devices Incorporated
Don ’t Care
1. The clock must be valid and stable meeting t CK specifications at least t CKSRE after entering
self refresh mode, and at least t CKSRX prior to exiting self refresh mode, if the clock is
stopped or altered between states Ta0 and Tb0. If the clock remains valid and unchanged
from entry and during self refresh mode, then t CKSRE and t CKSRX do not apply; however,
t CKESR must be satisfied prior to exiting at SRX.
2. ODT must be disabled and R TT off prior to entering self re fresh at state T1. If both R TT_NOM
and RTT_WR are disabled in the mode registers, ODT can be a “Don’t Care.”
3. Self refresh entry (SRE) is synchronous via a REFRESH command with CKE LOW.
4. A NOP or DES command is required at T2 after the SRE command is issued prior to the
inputs becoming “Don’t Care.”
5. NOP or DES commands are required prior to exiting self refresh mode until state Te0.
6. t XS is required before any commands not requiring a locked DLL.
7. t XSDLL is required before any commands requiring a locked DLL.
8. The device must be in the all banks idle state prior to entering self refresh mode. For example, all banks must be precharged, t RP must be met, and no data bursts can be in progress.
9. Self refresh exit is asynchronous; however, t XS and t XSDLL timings start at the first rising
clock edge where CKE HIGH satisfies t ISXR at Tc1.t CKSRX timing is also measured so that
t ISXR is satisfied at Tc1.

ODT must be held HIGH for at least ODTH4 after assertion (T1).
ODT must be kept HIGH ODTH4 (BC4) or ODTH8 (BL8) after the WRITE command (T7).
ODTH is measured from ODT first registered HIGH to ODT first registered LOW or from the registration of the WRITE
command with ODT HIGH to ODT registered LOW.
5. Although ODTH4 is satisfied from ODT registered HIGH at T6, ODT must not go LOW before T11 as ODTH4 must also be
satisfied from the registration of the WRITE command at T7.
