Input
Burst Chop: A12/ is sampled during Read and Write commands to determine if
burst chop (on the fly) will be performed. (HIGH - no burst chop; LOW - burst chopped).
On Die Termination: ODT (registered HIGH) enables termination resistance internal
to the DDR3/L SDRAM. When enabled, ODT is applied to each DQ, DQS, and
DM/TDQS, NU/
(when TDQS is enabled via Mode Register A11=1 in MR1) signal
for x8 configurations. The ODT pin will be ignored if Mode-registers, MR1and MR2, are
programmed to disable RTT.
Active Low Asynchronous Reset: Reset is active when
is LOW, and inactive

Data Strobe: output with read data, input with write data. Edge aligned with read data,
centered with write data. The data strobes DQS, DQSL, DQSU are paired with
Input/output differential signals ,
,
, respectively, to provide differential pair signaling
to the system during both reads and writes. DDR3/L SDRAM supports differential data
strobe only and does not support single-ended.
Termination Data Strobe: TDQS/
is applicable for X8 DRAMs only. When
enabled via Mode Register A11=1 in MR1, DRAM will enable the same termination

resistance function on TDQS/
that is applied to DQS/ . When disabled via

MR1.
