Description
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: For x16 only. If EMR(E10) = 0, A8 and E8 are UDQS# and
LDQS#. If EMR(E10) = 1, then A8 and E8 are not used.
Not used: For x8 only. If EMR(E10) = 0, A2 and E8 are RDQS# and
DQS#. If EMR(E10) = 1, then A2 and E8 are not used.
Reserved for future use: Row address bits A13 (x16 only), A14,
and A15.
