Description
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.
abled 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 differential data strobe mode is enabled.
Power supply: 1.8V ±0.1V.
DQ power supply: 1.8V ±0.1V. Isolated on the device for im-
proved noise immunity.
DLL power supply: 1.8V ±0.1V.
SSTL_18 reference voltage (VddQ/2).
Ground.
DLL ground: Isolated on the device from Vss and VssQ.
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 DQ4–DQ7; 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.
