Notes:
1. Pins B3 and A2 have identical capacitance as pins B7
and A8.
2. For a read, when enabled, strobe pair RDQS & RDQS#
are identical in function and timing to strobe pair DQS &
DQS# and input masking function is disabled.
3. The function of DM or RDQS/RDQS# are enabled by
EMRS command.
4. VDDL and VSSDL are power and ground for the DLL. It
is recommended that they are isolated on the device
from VDD, VDDQ, VSS, and VSSQ.
