Datasheet

TDQS, TDQS Output Termination Data Strobe : TDQS/TDQS is applicable for x8 DRAMs only. When enabled via Mode
Register A11=1 in MR1, DRAM will enable the same termination resistance function on TDQS/TDQS
that is applied to DQS/DQS
. When disabled via mode register A11=0 in MR1, DM/TDQS will provide
the data mask function and TDQS
is not used. x16 DRAMs must disable the TDQS function via mode
register A11 = 0 in MR1.
NC No Connect: No internal electrical connection is present.
VDDQ Supply DQ power supply: 1.35V, 1.283 - 1.45V operational; compatible to 1.5+/- 0.075V operation.
VSSQ Supply DQ Ground
VDD Supply Power Supply: 1.35V, 1.283 - 1.45V operational; compatible to 1.5+/- 0.075V operation.
VSS Supply Ground
VREFDQ Supply Reference Voltage for DQ
VREFCA Supply Reference Voltage for CA
