UDQS, (UDQS),

LDQS, (LDQS) x16

Input/

Output

Data Strobe: output with read data, input with write data. Edge-aligned with read data,

centered in write data. The data strobes DQS(n) may be used in single ended mode

or paired with optional complementary signals DQS(n) to provide differential pair

signaling to the system during both reads and writes. A control bit at EMR(1)[A10]

enables or disables all complementary data strobe signals.

DQS corresponds to the data on DQ0-DQ7

RDQS corresponds to the Read data on DQ0-DQ7, and is enabled by EMRS

command to EMR(1) [A11].

x16

LDQS corresponds to the data on DQ0-DQ7

UDQS corresponds to the data on DQ8-DQ15

No Connect: No internal electrical connection is present.
