Symbol

Type

Function

Active Low Asynchronous Reset: Reset is active when REET is LOW, and inactive when

REET is HIGH. REET must be HIGH during normal operation. REET is a CMOS rail to rail

signal with DC high and low at 80% and 20% of VDD, i.e. 1.20V for DC high and 0.30V.

Data Inputs/Output: Bi-directional data bus. DQ0 is the prime DQ in a low byte lane of x4/x8/x16

configuration and DQ8 is the prime DQ in a high byte lane of x16 configuration for write leveling.

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 differential signals ,

L, U, respectively, to provide differential pair signaling to the system during both reads

and writes. DDR3 SDRAM supports differential data strobe only and does not support single-

ended.

Termination Data Strobe: TDQS/T 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/T that is applied to DQS/. When disabled via mode register A11=0 in MR1,

DM/T will provide the data mask function and T is not used. x16 DRAMs must disable

the TDQS function via mode register A11=0 in MR1.

For x8,

Notes:

1. Input only pins (BA0-BA2, A0-A14, RA, A, WE, , CKE, ODT, and REET) do not supply termination.

2. The signal may show up in a different symbol but it indicates the same thing. e.g., /CK = CK# =  = CKb, /DQS = DQS# =

 = DQSb, /CS = CS# =  = CSb.
