Description
A0, A1, A2, A3, A4,
A5, A6, A7, A8, A9,
A10/AP, A11, A12/
BC#, A13, A14
Input
Address inputs: Provide the row address for ACTIVATE commands, and the column
address and auto precharge bit (A10) for READ/WRITE commands, to select one
location out of the memory array in the respective bank. A10 sampled during a
PRECHARGE command determines whether the PRECHARGE applies to one bank
(A10 LOW, bank selected by BA[2:0]) or all banks (A10 HIGH). The address inputs also
provide the op-code during a LOAD MODE command. Address inputs are referenced
to VREFCA. A12/BC#: When enabled in the mode register (MR), A12 is sampled during
READ and WRITE commands to determine whether burst chop (on-the-fly) will be
performed (HIGH = BL8 or no burst chop, LOW = BC4). See Table 69 (page 112).
BA[2:0]
Input
Bank address inputs: BA[2:0] define the bank to which an ACTIVATE, READ,
WRITE, or PRECHARGE command is being applied. BA[2:0] define which mode
register (MR0, MR1, MR2, or MR3) is loaded during the LOAD MODE command.
BA[2:0] are referenced to VREFCA.
CK, CK#
Input
Clock: CK and CK# are differential clock inputs. All control and address input signals
are sampled on the crossing of the positive edge of CK and the negative edge of
CK#. Output data strobe (DQS, DQS#) is referenced to the crossings of CK and CK#.
CKE
Input
Clock enable: CKE enables (registered HIGH) and disables (registered LOW) internal
circuitry and clocks on the DRAM. The specific circuitry that is enabled/disabled is de-
pendent upon the DDR3 SDRAM configuration and operating mode. Taking CKE
LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operations (all banks
idle), or active power-down (row active in any bank). CKE is synchronous for power-
down entry and exit and for self refresh entry. CKE is asynchronous for self refresh
exit. Input buffers (excluding CK, CK#, CKE, RESET#, and ODT) are disabled during
POWER-DOWN. Input buffers (excluding CKE and RESET#) are disabled during SELF
REFRESH. CKE is referenced to VREFCA.
CS#
Input
Chip select: CS# enables (registered LOW) and disables (registered HIGH) the
command decoder. All commands are masked when CS# is registered HIGH. CS#
provides for external rank selection on systems with multiple ranks. CS# is considered
part of the command code. CS# is referenced to VREFCA.
DM
Input
Input data mask: DM is an input mask signal for write data. Input data is masked
when DM is sampled HIGH along with the input data during a write access.
Although the DM ball is input-only, the DM loading is designed to match that of the
DQ and DQS balls. DM is referenced to VREFDQ. DM has an optional use as TDQS on
the x8.
ODT
Input
On-die termination: ODT enables (registered HIGH) and disables (registered LOW)
termination resistance internal to the DDR3 SDRAM. When enabled in normal
operation, ODT is only applied to each of the following balls: DQ[7:0], DQS, DQS#,
and DM for the x8; DQ[3:0], DQS, DQS#, and DM for the x4. The ODT input is
ignored if disabled via the LOAD MODE command. ODT is referenced to VREFCA.
RAS#, CAS#, WE#
Input
Command inputs: RAS#, CAS#, and WE# (along with CS#) define the command
being entered and are referenced to VREFCA.
RESET#
Input
Reset: RESET# is an active LOW CMOS input referenced to VSS. The RESET# input re-
ceiver is a CMOS input defined as a rail-to-rail signal with DC HIGH
≥ 0.8 × VDD and
DC LOW
≤ 0.2 × VDDQ. RESET# assertion and desertion are asynchronous.
