DQS8 are for ECC UDIMM only
CK and CK are differential clock inputs. All the DDR3 SDRAM addr/cntl inputs are sampled on the crossing of positive
edge of CK and negative edge of CK. Output (read) data is reference to the crossing of CK and CK (Both directions of
crossing)
Activates the SDRAM CK signal when high and deactivates the CK signal when low. By deactivating the clocks, CKE low
initiates the Power Down mode, or the Self-Refresh mode
Enables the associated SDRAM command decoder when low and disables the command decoder when high. When the
command decoder is disabled, new command are ignored but previous operations continue. This signal provides for
external rank selection on systems with multiple ranks.
When high, termination resistance is enabled for all DQ, DQS, DQS and DM pins, assuming the function is enabled in the
Extended Mode Register Set (EMRS).

DIMM designs, V
During a Bank Activate command cycle, Address input defines the row address (RA0-RA13)
During a Read or Write command cycle, Address input defines the column address, In addition to the column address,
AP is used to invoke autoprecharge operation at the end of the burst read or write cycle. If AP is high, autoprecharge is
selected and BA0, BA1, BA2 defines the bank to be precharged. If AP is low, autoprecharge is disabled. During a precharge command cycle, AP is used in conjunction with BA0, BA1, BA2 to control which bank(s) to precharge. If AP is
high, all banks will be precharged regardless of the state of BA0, BA1 or BA2. If AP is low, BA0, BA1 and BA2 are used
to define which bank to precharge. A12(BC) 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).
DM is an input mask signal for write data. Input data is masked when DM is sampled High coincident with that input data
during a write access. DM is sampled on both edges of DQS. Although DM pins are input only, the DM loading matches
the DQ and DQS loading.

7.1 Address Mirroring Feature
There is a via grid located under the DRAMs for wiring the CA signals (address, bank address, command, and control lines) to the DRAM pins. The length
of the traces from the vias to the DRAMs places limitations on the bandwidth of the module. The shorter these traces, the higher the bandwidth. To extend
the bandwidth of the CA bus for DDR3 modules, a scheme was defined to reduce the length of these traces.
The pins on the DRAM are defined in a manner that allows for these short trace lengths. The CA bus pins in Columns 2 and 8, ignoring the mechanical
support pins, do not have any special functions (secondary functions). This allows the most flexibility with these pins. These are address pins A3, A4, A5,
A6, A7, A8 and bank address pins BA0 and BA1. Refer to Table . Rank 0 DRAM pins are wired straight, with no mismatch between the connector pin
assignment and the DRAM pin assignment. Some of the Rank 1 DRAM pins are cross wired as defined in the table. Pins not listed in the table are wired
straight.

Figure 1illustrates the wiring in both the mirrored and non-mirrored case. The lengths of the traces to the DRAM pins, is obviously shorter. The via grid is smaller as well.
Figure 1. Wiring Differences for Mirrored and Non-Mirrored Addresses
Since the cross-wired pins have no secondary functions, there is no problem in normal operation. Any data written is read the same way. There are limitations however. When writing to the internal registers with a "load mode" operation, the specific address is required. See the DDR3 UDIMM SPD specification for these details. The controller must read the SPD and have the capability of de-mirroring the address when accessing the second rank. SAMSUNG
DDR3 dual rank UDIMM R/C B(2Rx8) and R/C E(2Rx8) Modules are using Mirrored Addresses mode.

NOTE :
1. For input only pins except
2. See "Overshoot and Undershoot specifications" section.
3. The ac peak noise on VRef may not allow VRef to deviate from VRefCA(DC) by more than +/-1% VDD (for reference: approx. +/- 15 mV).
4. For reference: approx. VDD/2 +/- 15 mV.
5. VIH(dc) is used as a simplified symbol for VIH.CA(DC100)
6. VIL(dc) is used as a simplified symbol for VIL.CA(DC100)
7. VIH(ac) is used as a simplified symbol for VIH.CA(AC175), VIH.CA(AC150), VIH.CA(AC135), and VIH.CA(AC125); VIH.CA(AC175) value is used when Vref + 0.175V is
referenced, VIH.CA(AC150) value is used when Vref + 0.150V is referenced, VIH.CA(AC135) value is used when Vref + 0.135V is referenced, and VIH.CA(AC125) value is
used when Vref + 0.125V is referenced.
8. VIL(ac) is used as a simplified symbol for VIL.CA(AC175), VIL.CA(AC150), VIL.CA(AC135) and VIL.CA(AC125); VIL.CA(AC175) value is used when Vref - 0.175V is
referenced, VIL.CA(AC150) value is used when Vref - 0.150V is referenced, VIL.CA(AC135) value is used when Vref - 0.135V is referenced, and VIL.CA(AC125) value is
used when Vref - 0.125V is referenced.
9. VrefCA(DC) is measured relative to VDD at the same point in time on the same device
