Description
Data strobe: Output with read data, input with write data for source synchronous oper-
ation. Edge-aligned with read data, center-aligned with write data. DQS# is only used
when differential data strobe mode is enabled via the LOAD MODE command.
Data strobe for lower byte: Output with read data, input with write data for source
synchronous operation. Edge-aligned with read data, center-aligned with write data.
LDQS# is only used when differential data strobe mode is enabled via the LOAD MODE
command.
Data strobe for upper byte: Output with read data, input with write data for source
synchronous operation. Edge-aligned with read data, center-aligned with write data.
UDQS# is only used when differential data strobe mode is enabled via the LOAD MODE
command.
Redundant data strobe: For 64 Meg x 8 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 dif-
ferential data strobe mode is enabled.
Power supply: 1.8V ±0.1V.
DQ power supply: 1.8V ±0.1V. Isolated on the device for improved noise immunity.
DLL power supply: 1.8V ±0.1V.

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: x8: these balls are used as DQ[7:4]; x4: they are no function.
Not used: If EMR(E10) = 0: x16, A8 = UDQS# and E8 = LDQS#; x8, A2 = RDQS# and A8 =
DQS#; x4, A2 = NU and A8 = NU. If EMR(E10) = 1: x16, A8 = NU and E8 = NU; x8, A2 = NU
and A8 = NU; x4, A2 = NU and A8 = NU.
Reserved for future use: Bank address BA2, row address bits A13 (x16 only), A14, and
A15.
