Description
Data strobe for lower byte: LDQS# is only used when differential data strobe mode is
enabled via the LOAD MODE command. Output with read data. Edge-aligned with read da-
ta. Input with write data. Center-aligned with write data.
Data strobe for upper byte: UDQS# is only used when differential data strobe mode is
enabled via the LOAD MODE command. Output with read data. Edge-aligned with read da-
ta. Input with write data. Center-aligned with write data.
Redundant data strobe: For the x8 configuration only. RDQS is enabled/disabled via the
LOAD MODE command to the extended mode register (EMR). When RDQS is enabled, RDQS
is output with read data only and is ignored during write data. When RDQS is disabled, ball
B3 becomes data mask (see DM ball). RDQS# is only used when RDQS is enabled and differ-
ential data strobe mode is enabled.
Power supply: 1.8V ±0.1V.
DLL power supply: 1.8V ±0.1V.
DQ power supply: 1.8V ±0.1V. Isolated on the device for improved noise immunity.
SSTL_18 reference voltage (V
Ground.
DLL ground: Isolated on the device from V
DQ ground: Isolated on the device for improved noise immunity.
No connect: These balls should be left unconnected.
No function: For the x4 configuration, these balls are no function. For the x8 configuration,
they are used as DQ[7:4].
Not used: If EMR(E10) = 0: For the x4 configuration, A2 = NU and A8 = NU. For the x8 con-
figuration, A2 = RDQS# and A8 = DQS#. If EMR(E10) = 1: For the x4 configuration, A2 = NU
and A8 = NU. For the x8 configuration, A2 = NU and A8 = NU.
Not Used: If EMR(E10) = 0: For the x16 configuration, A8 = UDQS# and E8 = LDQS#. If
EMR(E10) = 1: For the x16 configuration, A8 = NU and E8 = NU.
Reserved for future use: Bank address BA2, row address bits A[15:13].
