DATA INPUT/OUTPUT: DQ0~DQ17
data of DQ0 to DQ17 are outputted synchronizing with the both edges of QS output signal.
DATA STROBE: DS, QS
POWER SUPPLY: V
REFERENCE VOLTAGE: V
Method of data strobe is chosen by Extended mode register.
(1) Unidirectional DS / QS mode
(2) Unidirectional DS / Free running QS mode
The input data of DQ0 to DQ17 are taken in synchronizing with the both edges of DS input signal. The output

Both edges of QS are used for trigger signal of all DQs at Read operation. During Write, Auto-Refresh and
NOP cycle, QS assert always “Low” level.
Both edges of QS are used for trigger signal of all DQs at Read operation. QS assert always toggle signal.
This strobe type is easy to use for pin to pin connect application.
